摘要
用有限元法对单桩的锤击贯入过程进行了数值模拟，得到沉桩引起的土体动应力反应峰值，并以此作为土的前期固结应力，进行使用期桩土共同作用分析，得到桩基的承载特性．初步实现了在桩土共同作用分析中对沉桩影响的真正考虑．
In this paper,the finite element method is used to simulate the course of pile penetration,and the peak dynamic stress in the soil is obtained.With the peak value as the early stage soil consolidation stress,the bearing behavior of pile during operation can be obtained from the analysis of pile soil interaction.The influence of pile driving is considered for the first time in the analysis of pile soil interaction.The calculated results and the measured results are in good agreement,indicating the feasibility of the method of numerical simulation of pile driving and the method of analysis of pile soil interaction.
