SMW工法在软弱土地区深基坑支护中的组合应用

Combined Application of SMW Method in Deep Foundation Pit Support in Soft Soil Area

以天津软弱土地区某深基坑工程为例,围护桩采用灌注桩和SMW工法桩组合支护,据监测结果和现场施工反馈,组合支护型式满足基坑安全要求,有效降低基坑支护造价,显著缩短施工工期,为类似基坑工程的设计和施工提供参考。

A deep excavation located at the soft soil area of Tianjin is taken as an example,which supporting pile with cast-in-place pile and SMW method.According to the monitoring results and on-site construction feedback,the combination support type can meet the requirements of foundation pit safety,effectively reduces the cost,significantly shortens the construction,period and provides reference for the design and construction of similar foundation pit engineering.
