在分析现场沉降观测结果和有限元计算结果的基础上，对柔性荷载作用下水泥土桩 复合地基的承载力和沉降特性进行了分析研究，得出桩土应力比随时间、荷载性质、面积 置换率等因素变化的规律，以及沉降随时间荷载变化的特性，并分析了桩顶处存在的刺入 变形和土拱效应对复合地基承载力的影响．
Based on the analysis of the settlement and finite element results, the bearing capacity and settlement characteristics of cement-soil-pile composite foundation under flexible load are analyzed and studied. The results show that the stress-bearing ratio of pile-soil with time, load properties, area replacement rate And other factors, and the characteristics of subsidence with time. The influence of piercing deformation and soil arching on the bearing capacity of composite foundation is analyzed.
