Numerical Simulation of Pile-Soil Interaction Considering Sand Liquefaction under Earthquake

摘要：

　　Liquefaction is one of the most important damages in pile foundation under earthquake.However, it is very difficult to analyze.Numerical simulation of pile-soil interaction considering saturated sand liquefaction under earthquake is conducted using OpenSees program.In this model, the soil is divided into soft clay soil and saturated sand, and the single pile is embedded in the soil.The results show that the pore water pressure rises and the soil liquefied as vibration time increases.With the nonlinear of the soil develop, the stiffness, bearing capacity and the acceleration response of the soil and the pile decrease, while the displacement response of the soil increases.Therefore, it is necessary to consider the soil liquefaction in the design and analysis in the engineering practice.
