Abstract
Pile-driven operation is the essential means of flood control and river harnessing. Anti-flood Spiral Pile is an innovative flood fighting and rescue equipment. Based on the experiment, established the spiral pile finite element model in FEM method and constructed the soil model with SPH smooth particles, set the keywords and parameters by using LS-DYNA softwares own processor, and then, the large deformation (soil extrusion and shearing status, etc.) and stress conditions be simulated truthfully. With reference to the experiment, the simulation results of SPH method with ALE method was contrasted, which could provide a reliable reference and scientific basis for the subsequent analysis and design of the spiral pile.
