CFG桩复合地基设计的工程应用

CFG桩复合地基是由CFG桩、桩间土和褥垫层一起构成的刚性桩复合地基。通过褥垫层把桩和基础断开,改变了过分依赖桩承担垂直荷载和水平荷载的传统设计思想,其优点体现在其传递水平荷载和垂直荷载的工作特性上。CFG桩复合地基设计,必须同时满足强度和变形两个条件。CFG桩复合地基技术以其用材经济、施工快捷、加固效果良好等优点,在工程上得到了广泛的应用。

Engineering Application on the Design of Cement Flyash Gravel Piles Composite Fo undation

Cement Flyash Gravel Piles composite foundation is a rigid piles compo site foundation which is composed of Cement Flyash Gravel piles, pile gap soils, and feeble foundation. The traditional design idea that upright bearing load a n d horizontal bearing load of piles can be depended overmuch is changed, through disjoining piles and foundation by feeble foundation. The advantages are embodi e d by the characteristics of transferring horizontal bearing load and upright bea ring load. The design of Cement Flyash Gravel composite foundation is widely ap p lied on many projects because of its advantages, for example, using materials ec onomically, constructing rapidly, excellent reinforcing effects, et al.
