摘要
膨胀土作为特殊土,其遇水膨胀、失水收缩性质给基坑支护施工造成较大困难,本文通过监测昆明市区某基坑工程施工过程及工后变形,对不同支护结构在膨胀土层的变形特点进行分析总结,为本地区膨胀土层深基坑工程设计与施工提供参考与借鉴。
It’s more difficult to ensure safety of deep foundation pit support in expansive soil area than usual.By comparing monitoring deformation data of post-construction and during construction of an example in Kunming.Analysis and optimization the deformation characteristics of deep foundation pit support in expansive soil.The conclusions are expected to provide reference for design and construction of similar projects in the future.
