摘要
总结了刚性基础下CFG桩复合地基中褥垫层的作用机理,采用数值模拟的方法研究了柔性基础下褥垫层的不同工作特点,对褥垫层的合理设置提出了几点建议。
The author generalized the working mechanism of granular material cushion of CFG pile composite foundation under rigid foundation. The difference between the former and embankment loads is analyzed with finite element modeling method. Some suggestions on cushion setting are offered.
