摘　　要：以有限单元法为理论基础,利用ANSYS软件建立水闸天然地基承载模型、单桩承载模型以及群桩复合闸基承载模型来模拟静载过程,通过加载分析得到地基的荷载-沉降曲线以及桩身压缩曲线,并据此推出确定复合地基承载力的标准,再与水闸地基最大容许沉降等参数进行比较,最终得到进行水泥土搅拌桩复合闸基设计的控制指标。Based on the finite element method as the theoretical basis, the sluice natural foundation load-bearing numerical model, the single pile load-bearing numerical model and the composite foundation load-bearing numerical model are established with ANSYS to simulate the load-bearing process in this paper. Through the analysis, the load-settlement curve and the pile compression curve have been obtained. Then the composite foundation bearing capacity＇s determined standard can be received. Compared with sluice foundation maximum allowable settlement parameters, the design control index of the cement-soil pile composite foundation can be determined in the end.
