Abstract
Results of pilot laboratory, field and analytical studies on stability of slopes are presented. The analysis of a condition of slopes is made in connection with construction of the alpine skiing track in the natural boundary the Cook Zhaylau to Alma-Ata, Kazakhstan. Researches are conducted in the conditions of static and seismic impact on slopes. Laboratory researches are executed in a special tray of 200x1500x800(h) mm where natural soil – collapsible loam was modelled by specially picked up composition of soil. The configuration of slopes is picked up on actual by data geodetic measurements и geological researches. Special powder sensors are applied to fixing of destructions in a tray. As a result of researches platforms on which there is a destruction of slopes are visually recorded. Regularities of their formation depending on location and force of static influence, and also for seismic influence with a force of 8 and more than points on a scale MSK 1964. In addition on slopes analytical calculations with use to the Calculation of Stability of Slopes and Plaxis programs are executed. Calculations are executed on static and seismic influences. Data on coefficient of stability and registration of isolines of tension and deformations are obtained. Comparison of experimental and settlement data allowed to increase the accuracy of definition of some boundary conditions put at experimental modeling of slopes and to increase reliability of calculations for determination of coefficients of stability.
