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．计算结果与实测结果的较好吻合验证了本文锤击沉桩数值模拟及考虑沉桩影响的桩土共同作用分析方法的可行性
The finite element method was used to simulate the penetration process of single pile, and the peak value of dynamic stress response caused by pile driving was obtained, which was used as the consolidation stress of soil. The bearing characteristics of pile foundation are obtained. The real consideration of the influence of pile driving in the analysis of pile-soil interaction is initially achieved. The calculated results are in good agreement with the measured results, which verify the feasibility of numerical simulation of hammer piling and pile-soil interaction analysis considering the influence of pile driving.
