本文以自升式海洋平台桩靴为主要研究对象，运用Ansys Workbench中的Design Modeler建立桩靴与土的模型，通过LS-DYNA来模拟桩靴上拔过程，并计算了3种桩靴形式的拔桩力和研究了3种桩靴的上拔过程土体的变形，并将桩靴上拔阻力的理论计算值与数值模拟计算的结果进行比较分析。本文对未来海洋平台的发展有一定的工程意义。
In this paper, using Ansys Workbench Design Modeler to establish pile shoe and soil models as main research object. Then simulating the pile shoe pulling process byLS-DYNA. And calculate three kinds of Pile-pulling force and the deformation of soils during the three pile-jacking process. Then compare the theoretical calculation value of pile-up resistance with the result of numerical simulation and analyze. This article has a certain engineering significance for the development of offshore platforms in the future.
