利用FLAC3D有限差分软件对地基土在地震作用下孔隙水压力的变化进行了流固耦合分析,探讨了地基土在地震作用下孔压的变化规律,结果表明地基孔隙水压力的分布与地震激励、场地土的土质、组成和埋藏条件等因素都有密切关系,对进一步加深液化地基震害的理解具有重要的意义。

This paper carries out fluid-solid interaction analysis on porewater pressure variation of foundation soil under the earthquake by using FLAC3D finite difference software, and explores the porewater pressure variation of foundation soil under the earthquake. Results show that the foundation porewater pressure distribution is closely related to seismic excitation, field soil quality, composition and embedding conditions and so on, which has significant meaning for further understanding hydraulic foundation earthquake hazard.
