南宁某建筑软弱地基处理方案分析

Analysis of Soft Ground Treatment Scheme of a Building in Nanning

基础设计中,经常会遇见软弱地基。论文介绍了常用的几种软弱地基的处理方法,如换填垫层法、水泥粉煤灰碎石桩法、水泥土搅拌桩法等,并分析了每种地基处理方法的适用条件。论文结合南宁某工程案例,介绍该工程的地质条件,分析其工程特点,指出该工程适合软弱地基的处理方法为换填垫层法和水泥土搅拌桩法。最后,给出换填垫层法的具体做法,水泥土搅拌桩的计算公式及计算结果。

In foundation design,we often meet soft foundation.This paper introduces several common soft soil ground treatment methods,such as replacement layer of compacted fill method,cement fly ash-gravel pile method,cement deep mixed column method and so on,and analyzes the applicable conditions of each ground treatment method.Combined with a project case in Nanning,the paper introduces the geological conditions of the project and analyzes its engineering characteristics,points out that the suitable soft soil ground treatment methods for the project are replacement layer of compacted fill method and cement deep mixed column method.Finally,the paper gives the specific details of replacement layer of compacted fill,the calculation formulas and results of cement deep mixed column.
