摘要
强震动条件下液化土同构筑物的相互作用问题具有非线性和复杂性等特点,基于动态土工离心模型试验应用有效应力动力有限元来研究,即应用非线性动力有限元FLIP解析土工离心模型试验结果,对比分析来再现建于液化土地基上的实际栈桥式基础在大地震下的破坏程度、状态和机制,取得了较好成果。
The problem of interaction between the structure and liquefiable soil is an non-linear and complicated problem. Based on the geotechnical centrifuge model test, the problem was investigated by the finite element program FLIP (Finite element analysis of Liquefaction Program) developed with effective stress method. Moreover, the results obtained from the experiment were compared with those from the simulation. And the failure degree, state and mechanism of the prototype pile-supported structure in the liquefiable soils under the strong shaking condition were also discussed. This study provides a reliable foundation for the seismic design of the large scale port structures.
