    A method for analyzing the uncertainties involving the use of empirical relationships in design is developed. It is applied to evaluate the reliability of the relationship su(mobilized)=
    0.22σ'p
    (measured), whereby the pertinent uncertainties are analyzed using extensive laboratory and field observed data. On the average, the relationship su(mobilized)=
    0.22σ'p
    (measured) is unbiased and the error implicit in the relationship is about 15%. When cone values are used to infer s'p, additional uncertainties on the mobilized undrained strength will incur resulting mainly from the calibration uncertainty between σ'p and the cone values. Alternatively, vane tests may be performed to infer the mobilized strength using Bjerrum correction factor. Results show that uncertainty level associated with using the vane tests is smaller than that using the cone values, provided that similar scatter is observed between measured vane and cone values at a given site. However, prediction of the mobilized strength is even more accurate if direct measurements can be made on the preconsolidation pressure. The proposed probabilistic method also assesses the benefit of additional tests besides comparing the accuracy of using various soil parameters for predicting mobilized undrained strength. Such information is essential for planning cost-effective site characterization program.

    L'entree en Iran des armees britannique et sovietique s'est produite en aout 1941. Elle ebranla du coup le regime de la dynastie pahlavi qui etait au pouvoir depuis 16 ans, et mena le pays vers l'instabilite politique et le chaos social. La defaite de l'arme gouvernementale, qui etait le pivot du regime de Reza Shah, reduisit considerablement le controle du gouvernement central dans le pays. Cette situation politico-sociale confuse permit le developpement de differents mouvements politiques en Iran. C'est ainsi que le 16 aout 1942 le parti clandestin Komeley Jiyanewey Kurdistan (J-K) est ne a Mehabad, une ville au nord-ouest de l' Iran. Des sa formation, ce parti a su etendre sa sphere
    d'activite
    et, en une courte periode de temps, a fini par mettre sous son influence la ville et ses alentours. A la fin de la Seconde Guerre mondiale, en ete 1945, le J-K etait devenu une organisation representant le mouvement nationaliste kurde en Iran. C'est a ce moment-la qu'un autre parti politique, le Hizbi Dimokratiki Kurdistan (HDK), fonde par Qazi Mihemed a Mehabad aussi, devait remplacer le J-K. Des le
    22
    janvier 1946, le HDK proclama l'instauration de la≪Republique de Kurdistan≫. Cependant, les troupes sovietiques qui avaient pris sous leur protection la Republique evacuerent les terres iraniennes, en mai 1946. Six mois plus tard, sous la pression militaire du gouvernement central iranien, la republique s'ecroula. Deux theories tentent
    d'expliquer
    le passage du J-K au HDK. William Eagleton Jr., par exemple, affirme dans The Kurdish Republic of 1946 que le HDK a ete cree sur le conseil des autorites sovietiques. L'ex-secretaire general du Parti Democratique du Kurdistan
    d'Iran
    , 'Ebd el-Rehman Qasimlu maintient par contre que Qazi Mihemed a etabli le nouveau parti de sa propre initiative, eu regard a la situation politique de cette epoque-la. Il considere que la passage du J-K au HDK comme etant l'evolution
    d'un
    parti nationaliste clandestin en un parti democratique. En analysant ces deux theories et en se basant sur les autobiographies des personages qui se sont engages dans cet evenement, cette etude tentera
    d'examiner
    le principe directeur et les activites du J-K et de mieux comprendre les raisons pour lesquelles le J-K devait etre remplace par le HDK. La conclusion generale portera sur les differents objectifs politiques du J-K et du HDK. Le J-K visait l'elevation du niveau culturel du peuple tout en luttant contre le tribalisme, qui etait, selon lui, le probleme majeur de≪la nation kurde≫, et cela en ecartant toute idee de revolte militaire. Le J-K a aussi exclu de son cadre les elites sociales telles que les leaders des tribus et dirigeants religieux de peur qu'ils n'excercent une influence sur les membres du parti. L'automne de 1944 fut le debut
    d'une
    nouvelle ere pour le mouvement kurde. Alors que l'espoir de l'autodetermination augmentait parmi le peuple a mesure que s'approchait la fin de la guerre, la necessite de la force militaire a commence a se faire sentir dans le J-K. C'est pour cela que s'est produite au sein du parti une tendance a compter sur l'aide militaire des sovietiques et a recourir au leadership de Qazi Mihemed, qui avait une certaine influence meme sur les leaders tribaux. Mais cette tendance etait essentiellement incompatible avec la ligne fondamentale du J-K et, graduellement, a prive ce parti de sa raison
    d'etre
    . Ainsi, le HDK se substitua au J-K en tant que≪parti democratique≫visant a rallier
    d'abord
    les elites sociales sous sa banniere, en s'appuyant sur l'autorite personnelle de Qazi Mihemed.

    The pseudo-static analysis has been used in engineering practice to simplify the computation of the upper limit of a slope under seismic load. In this paper, the upper bound technique of limit analysis of perfect plasticity is used to determine the bearing capacity of a foundation near a down-hill slope. In this analysis (Chen et al., 1969; Chen, 1975), a logarithmic spiral rapture (Abdul-Baki et al., 1970; Sawada et al., 1984) is assumed to start at an edge of the loaded area far from the slope. A landslide is assumed to be of rigid body type with the inertia force acted at its center of gravity. The collapse state is reached when the rate of kinematic energy of the landslide together with the load is equal to the rate of dissipation of internal energy along the sliding surface. This energy balance leads to the equation of ultimate load with several parameters. The optimized numerical rcsults with respect to these parameters are compared with those by Kotter's method (Yamaguchi, 1959) and those obtained by the slice method.

    This paper presents reinforcing mechanisms and a method for analyzing reinforced earth structures. The reinforcing mechanism presented is divided into two stages, a fixed slip surface and an arbitrarily selected slip surface. The mechanism is studied through direct shear tests and plane strain compression tests including some geotextiles. The reinforcing materials considered in this paper only have tensile strength. The authors have already proposed a method called Generalized Limit Equilibrium Method (GLEM) for analyzing stability problems. The validity of the method has already been shown in previously published papers. In this paper, the method is extended to carry out a stability analysis for reinforced earth structures. Finally, large scale model tests for the bearing capacity of foundations on reinforced slopes were carried out to investigate the validity of the proposed reinforcing mechanism and the analytical method. Through comparisons of observations of experiments and results of the analytical method, the validity of the present work is demonstrated.

    It has been shown after mathematical and mechanical investigation that Limit Equilibrium Method (LEM) can be considered as a method to obtain the necessary condition of Slip Line Method (SLM), and that the solution can be obtained under the condition that Fs=1 and ∂Fs/∂θ=O, where Fs is the safety factor and θ is the inclination of the plane on which the safety factor is defined. Next, the generalized LEM (GLEM) is proposed, dealing with the following points : (1) Triangular or quadrangular blocks can be treated; (2) Safety factors are defined also on interblock planes; and (
    3
    ) All types of plastic problems, slope stability, bearing capacity, and earth pressure are identically formulated. Two situations regarding treatment of the moment equilibrium condition are discussed. GLEM is applied to well-known problems. The results agree well with those obtained by theoretical methods. GLEM can be used to obtain the distribution of earth pressure or bearing capacity. GLEM, Iike ordinary LEM, is very effective for the practical problems, but GLEM is more theoretical and it can result in more accurate solutions.

    1. The chromosome numbers of 64 species have been studied on which 56 are investigated for the first time.
    2. Morphological, anatomical and cytological findings on the Musaceae in the broad sense are considered from a phylogenetical standpoint and three distinct groups:
    a) Musa-Ensete, b) Ravenala-Strelitzia-Phenakospermum and c) Holiconia are recognised as suggested by some authors. For these groups sub-familial status is proposed.
    3
    . Lowiaceae have been studied for the first time cytologically and their chromosome morphology, distinct from that of any other group of Zingiberales, confirms their claim to familial status.
    4
    . Consideration of the conflicting theories proposed to account for the higher chromosome number in genera like Globba, Alpinia, and Phaemeria, etc. leads to rejection of Chakravorti's hypothesis of wholesale fragmentation of chromosomes and the acceptance of the opposed view of Raghavan and Venkatasubban and others.
    5. Holttum's transference of the genus Zingiber to the tribe Hedychieae has been given cytological support on the following points:
    a) the basic number in the genus Zingiber correlates with that of Kaempferia.
    b) the new tribe Alpinieae (which is infact Zingibereae without Zingiber) have consistently 48 chromosomes in their somatic complements.
    6
    . It is suggested that the African representatives of Kaempferia should be given the status of genus; Cienkowskya on the following points:
    a) the difference in floral morphology
    b) geographical separateness and
    c) the difference in the number and morphology of the chromosomes. By comparing the present and past findings, various lines of evolution of the chromosome complements within each group are discussed.
    7. The basic number 11 is considered to be probably the original one for the Zingiberales as a whole, being present in Ravenala which is the most primitive member in the order. From this secondary basic numbers have arisen through evolution.

    The bearing capacity and compressibility of a calcareous sand were examined by drained triaxial compression tests and laboratory model tests on strip footings 51mm by 305mm. The tests were carried out on two sands-a calcareous sand having a carbonate content of 18% and a clean sand obtained by washing the calcareous sand with Hydrochloric Acid (HCI) and water. All tests were performed at a relative density of 66%. The results indicate increased compressibility and no change in the peak strength parameters due to the presence of carbonates. The bearing capacity of the calcareous sand was smaller than that of the clean silica sand. Various methods of analysis were discussed to account for the effect of compressibility on bearing capacity.

    The filtration compatibility of soil-geotextile systems has been assessed experimentally in the laboratory with the gradient-ratio test. A nonwoven geotextile was used against a variety of model soils that were prepared from glass beads. They exhibited a range of fines content, in both gap-graded and broadly-graded size distributions. Filter blinding and clogging, if it happens, occurs within hours of initiating unidirectional flow. The zone of soil above the geotextile that is influenced is relatively thin. In gap-graded soils, the movement of fine particles appears to occur at a conditioh of

    This paper focuses on an extension of the log-spiral analysis of bearing capacity that has been presented in the authors' previous work for strip foundations placed on the level ground, to those on the top of slopes. Comparisons are made with other analytical and experimental results to examine applicability of the method to practical problems. It is revealed that the log-spiral analysis somewhat overestimates bearing capacity values as compared to other solutions, the errors involved being around 20 percent at maximum and varying sensitively to the angle of internal friction and slope inclination. Also noticed is a relatively good correspondence with experimental results, especially with model tests on clay (φ=0), on both the ultimate bearing capacity and the shape of sliding surfaces.

    In order to simulate the formation of localized shear bands, which is commonly observed during large deformation of soils, we first present a systematic extension of the well known Cam-clay model developed for small strains to the model for finite strains/deformations and then incorporates a non-coaxial term in the model. Finally, confining the deformation to undrained plane strain conditions, we examine the effects of the non-coaxial term on the shear bands formation.
