摘要
在评述现有相关研究成果的基础上 ,针对基底反力的分布特征 ,用弹塑性有限元方法分析变刚度复合地基处理方案对基础最大沉降、差异沉降、筏板弯矩等主要工程特性的影响。从经济性和尽量减小基础差异沉降的角度出发 ,提出地基变刚度调平处理的优化设计原则 。
The development of compound foundation with variable rigidity is reviewed. According to the feature of base reaction, three types of soil treatment schemes under rafts are researched with finite element method. Influence of soil treatment on maximum settlement and differential settlement of foundation as well as bending moment of raft is analyzed. From an economical point of view, an optimal scheme of ground improvement with variable rigidity for minimizing the differential settlement of foundation is put forward,which may be a guide to design of actual projects.
