摘要
成达综合楼工程基坑开挖支护和地基加固处理,在成都地区对卵石土地基的加固处理具有一定的代表性,从场地实地岩土性状着手,查明软弱夹层分布范围,对工程设计方案通过一系列的定量分析,经过旋喷桩加固处理后,使软弱夹层达到稍密卵石层的强度,对类似工程的地基处理具有一定的参考价值。
Foundation pit excavation supporting and ground reinforcement engineering construction case history of Chengda comprehensive mansion have certain representative to reinforcement treatment of cobble-gravel soil foundation in Chengdu region. According to soil characters in the field, and finding out distribution range of weak interlayer, through a series of quantitative analysis of engineering design scheme, it enables the strength of weak interlayer reaches to that of slightly dense cobble-gravel layer after reinforcement treatment using jet grouting pile. It has certain referential values for foundation treatment in similar engineering projects.
