水泥搅拌桩复合地基承载力特征值确定方法的探讨

摘要

水泥搅拌桩造价低、施工速度快、能发挥桩土共同作用力，在处理软弱地基时，往往容易受到设计影响。本文通过一些工程试验数据，结合相关规范，阐述在试验过程中如何正确地确定复合地基承载力特征值。%cement mixing pile has low cost and fast construction speed.Joint effect of pile and soil can be exerted by it. When soft foundation is treated,it is always affected by design easily.In the paper,related specifications are combined for describing how to correct determine composite foundation bearing capacity characteristic value in the testing process through some engineering test data.
