摘要
以数值模拟的方法研究了变刚度复合地基的沉降分布和变形影响范围。计算结果表明:在荷载较大的核心筒区密集布桩而在荷载较小的边角区稀疏布桩或不布桩,能有效的减少基础沉降差,同时减少基桩工程量。
The behaviors of composite piled foundation with variable stiffness are studied in this paper by FEM,such as settlement pattern,effect scope.The results indicates that the differential settlement and volume of piles can be reduced efficiently when the raft is piled more in high loading zone and less in low loading zone or not.
