摘　　要：文章基于多物理场仿真软件COMSOL Multiphysics"岩土力学模块",对打桩过程进行模拟分析。为了方便建模,将H300*300型工字钢钢板桩近似为φ20cm,长300cm的圆柱桩,并应用小孔扩张理论,通过建模分析在距离承台3m处打桩过程的挤土压力,为实际打桩施工提供一定的理论参考。This paper is based on the “geotechnical mechanics module”to simulate and analyze the pile-driving in COMSOL Multiphysics. In order to facilitate modeling, the H300*300 I-steel is approximately as a cylindrical pile which diameter is 0.2 meter and 3 meter long. The result through modeling the pile-driving 3 meter far from cushion cap with the theory of pinhole expansion is used for reference in real pile-driving.
