为了研究刚性桩复合地基的抗震性能，提出了微探针群刚性桩复合地基地震反应的三维有限元分析方法。采用三维有限元方法分析了群桩刚性桩复合地基在地震作用下的动力响应规律，特别是桩身内力响应。值得注意的是，当桩的内力响应明显减小时，整个桩的最大内力也明显小于桩基的最大内力。然而，当桩体位于层状地基上，且相邻土层的弹性模数相差较大时，地震作用会使桩体产生较大的内力。刚性桩复合地基的抗震性能是可行的，可以推广应用于其他复合地基的类似抗震性能试验。
In order to study the seismic performance of the rigid pile composite foundation, a three-dimensional finite element analysis of the seismic response of the rigid pile composite foundation with microprobe group was proposed. The three-dimensional finite element method is used to analyze the dynamic response law of pile group rigid pile composite foundation under the action of the earthquake, especially the internal force response of the pile body. It is worth noting that when the internal force response of pile decreases significantly, the maximum internal force of the whole pile is also significantly smaller than the maximum internal force of pile foundation. However, when the pile body is located on a layered foundation and the modulus of adjacent soil layers differs greatly, the earthquake action will cause the pile body to generate a large internal force. The seismic performance of the rigid pile composite foundation is feasible, and it can be extended and applied to the similar seismic performance test of other composite foundations.
