摘　　要：深厚软土地区的地基很难满足建筑结构地基承载力和变形的要求,刚性桩复合地基为常用的地基处理措施。基于实际工程案例,对复合地基的失稳以及桩体破坏模式进行了研究,对不同的路堤稳定性计算方法和沉降的计算方法进行了对比分析,并且提出了一种基于桩体不同破坏模式的地基稳定性优化算法。The bearing capacity and deformation of natural foundation encountered in many projects are difficult to meet the requirements of building structures,especially in deep soft soil areas,as such rigid pile composite foundation is a common foundation treatment measure.Based on some engineering examples,in this paper the instability of composite foundation and the failure mode of pile are analyzed,several common calculation methods of composite foundation stability are compared and analyzed,and a foundation stability optimization algorithm based on different failure modes of pile is proposed.
