摘　　要：复合地基由于具有良好的经济性和适用性,得到了越来越广泛的应用,目前复合地基的设计也逐渐由承载力控制转变为沉降控制。在现有的复合地基理论中,大都以刚性基础为前提,没有考虑基础刚度的影响。利用数值方法,研究了在不同刚度基础下复合地基中应力场和位移场的差异。Due to its economic efficiency and good feasibility, composite foundations have found wide application. The design of composite foundations has changed from load-carrying capacity control to subsidence control. In most theories of composite foundation, the foundation is assumed to be rigid and the influence of foundation stiffness is neglected. In this paper, numerical methods are used to investigate the influence of foundation stiffness on the stresses and deformation of the composite foundation, highlighting the discrepancy.
