SMW工法桩基坑围护体系中钢支撑对降低基坑变形风险的作用分析

Analysis on the Effect of Steel Bracing in SMW Pile Foundation Pit Retaining Structures on Reducing the Risk of Deformation

以工程实例为背景,以基坑监测数据为依据进行整理和分析,探究基坑变形特点,重点阐述在SMW工法桩基坑围护体系中钢支撑的重要作用,分析和总结该围护体系下的基坑变形情况和施工中遇到的难题,针对施工过程中基坑直接暴露阶段的变形风险,给出相应的施工措施。

Based on the detailed monitoring data obtained during the construction,the project case is taken as the background to sort out,analyze,and explore the deformation characteristics.This paper focuses on the important role of steel support in the SMW pile foundation pit retaining structures and the deformation risk in the direct exposure stage ofthe foundation pit during the construction,analyzes and summarizes the deformation offoundation pit under the retaining structures and aiming at the problems encountered in construction,gives the corresponding construction measures.
