深层水泥搅拌复合地基的桩土荷载分担探讨
Study on Load Distribution of Pile and Surrounding Soils in Composite Ground Mixed with Cement in Depth
-
摘要: 笔者根据深层水泥搅拌复合地基载荷试验资料，对桩土应力及荷载分担进行了分析探讨。提出桩土应力比为3.2~5.2,桩土荷载分担为75%~80%和20%~25%。此结果在工程实践中得到验证，可作深层水泥搅拌加固地基设计时参考。Abstract: Based upon the results of load test for composite ground mixed with cement in depth, a study is carried out and there come the results that the stress ratio of the pile and surrounding soils is 3.2~5.2 and the load distribution on the pile and soils is 75~80% and 20~25%。The results have been verified by some engineering practice and may be used as a reference to the ground reinforcement with cement in depth.
