This paper is concerned with the problem of a single pile subujected to relatively large lateral loads. In such a problem, the load-deflection relationships of piles are mainly governed by the progressive yielding of the soil surrounding the loaded pile and elastic-plastic state developed in the pile But we have known few studies considered both of two conditions mentioned above. Hence, the authors propose the method of analysis for lateral loaded piles derived from the transfer matrix method, and report the results compared with two samples (Test No.1 and No.2) in model tests carried out in sand. The results obtained are summarized as follows. (1) On the load-deflection relationships, the computed results are probably corresponding with the observed, as shown in fig.15 (2) The maximum bending moment and its depth obtained by proposed method approximate quite to the results transformed from strains measured along pile axis in test No.2. (3) At the ultimate state, results obtained by proposed method indicate better approximation to test results than those by Brom's theory.
