    Abstract

    In this paper, an in-situ experiment under lateral static, cyclic, and dynamic loadings, on a large sized steel pipe pile in soft silty clay on the downstream of the Yangtze River and static and dynamic triaxial tests on soil samples in the laboratory are described, and the pile-soil interaction behavior is analyzed and discussed. In the analysis, the finite-element method and other simplified methods are compared using different models of lateral soil stiffness. From the results of the tests as well as the analysis, a possible formulation of the p-y curves of the pile in soft clay under lateral loadings is suggested, and a simplified method of dynamic analysis taking into account the pile-soil interaction is also proposed.
