杭州软土地区某邻近地铁隧道深基坑变形监测分析

Deformation Monitoring Analysis of a Deep Foundation Pit Adjacent to a Subway Tunnel in Hangzhou Soft Soil Area

为研究深基坑开挖对周围环境的影响,文中以杭州某软土地区某深基坑工程为例,结合施工现场的监测数据,对基坑开挖全过程中周围环境的变形特性、支护结构变形及支撑轴力变化情况进行分析,以期为同类型基坑的设计和施工提供参考。

In order to study the influence of deep foundation pit excavation on the surrounding environment,taking a deep foundation pit project in a soft soil area of Hangzhou as the background,combined with the monitoring data of the construction site,the deformation characteristics of the surrounding environment,the deformation of the supporting structure and the change of the supporting axial force during the whole process of foundation pit excavation are analyzed,which provides reference for the design and construction of related types of foundation pits.
