摘　　要：考虑带帽控沉疏桩复合地基力学性状规律的多种影响因素,采用非线性有限元方法,对带帽控沉疏桩复合地基力学性状进行了较深入的数值模拟分析,得到了带帽控沉疏桩复合地基力学性状的一些基本规律,为其理论研究、工程设计与施工提供有益参考。Taking some factors influencing mechanical behavior rules of a composite foundation of control settlement and sparse piles with caps into consideration, the mechanical behaviors have been analyzed by means of nonlinear finite element method（FEM）, some basic rules of mechanical behaviors have been obtaind. The results can provide the useful guidance for the theory research, engineering design and construction.
