摘要
结合广东高明污水池地基沉降,分析了强夯法处理深厚软土地基存在的工后沉降偏大的原因;并根据现场某一时间段的沉降观测资料结合太沙基固结理论,得到当前地基的固结度;在充分利用地基因发生的固结而增加的地基承载力基础上,设计了地基的加固方案,做到"缺多少补多少"的地基加固理念,为类似地基加固工程提供参考。
Combined with Guangdong Gaoming Sewage Pool foundation settlement, this paper analyzes the reasons of larger post-construction settlement in deep soft foundation treatment with dynamic consolidation; obtains the consolidation degree of the current foundation according to site settlement observation data during a certain period and combined with Terzaghi consolidation theory; plans foundation consolidation program according to the foundation reiforcement concept of ＂Makeup for Shortage＂ to provide reference for the similar foundation consolidation engineering.
