Settlement Calculation of CFG Composite Foundation

摘要: 沉降计算是CFG桩复合地基的设计关键,目前大多数工程采用规范建议的沉降计算方法,但是该方法计算出的沉降量和实测值有很大的差距,有时候远远大于实测值.为此,在现行规范法计算复合地基沉降的基础上,提出了一种新的实用简化计算方法,该法可考虑桩侧摩阻力及桩端土的性质.最后,利用实际工程对本文提出的方法进行了验证,证明了其准确性.Abstract: The status and development of settlement calculation methods of CFG pile composite foundation are analyzed.The main questions of CFG pile composite foundation are pointed.This paper optimizes one simple calculating method considering the mutual action of pile and the earth.Compared with engineering sample,the calculation results are well consistent with the practice.
