摘要
该文提出带柱墩的筏板基础设计方法,取消传统独立扩展柱基加防水板基础的褥垫层,考虑防水板的分担作用。通过理论分析和有限元计算,获得不同地基条件、不同筏板厚度及不同基础尺寸情况下,筏板分担的基本规律。同时,给出该方法的适用范围,供设计人员参考。
A new type of foundation named ＂Stump-raft foundation＂ is presented in this paper. It is different with the traditional independent foundation plus waterproof board for canceling the soft cushion laid below the foundation and considering the sharing load of waterproof board. Based on the theoretical analysis and finite element method calculation, the load sharing ratio of stump and raft under different preconditions has been studied. The application conditions of this new foundation have been proposed for reference to designers.
