摘要：
To examine the applicability of the p-y curve of a single pile-soil interaction in soil liquefaction to pile group foundation, a numerical model of the seismic response of a pile group-soil coupled system in soil liquefaction is developed in this paper based on the open system for earthquake engineering Simulation finite element method platform and verified by the test results of centrifugation. Then, the reliability of the p-y curve in the p-multiply factor method in the analysis of the pile group-soil interaction in soil liquefaction is discussed based on the verified numerical model. Finally, the p-y curve in the current p-multiply factor method is modified through repeated numerical simulations and analyses, adopting pile spacing as the control index. Accordingly, a new p-y curve of the pile group-soil interaction in soil liquefaction is proposed, which considers the pile spacing effect. The correctness is verified by the test results of centrifugation. Copyright ©2021 Journal of Harbin Engineering University.
