用反射片配合全站仪监测基坑围护结构深层水平位移理论研究

在深基坑开挖过程中,监测为安全施工保驾护航,对施工工艺、参数的调整起着指导性作用,为优化设计及今后的类似工程积累经验,提供参考依据。围护结构深层水平位移监测是基坑安全监测最重要的项目之一,但施工过程中不可避免的会造成测斜管破坏,使得围护结构位移无法监测。本文从理论上分析研究,证明了用反射片配合全站仪可以对围护结构深层水平位移进行补救监测。

In the process of deep foundation pit excavation, monitoring is the escort security construction, the construction process, parameter adjustment plays a guiding role, in order to optimize the design and the experience of similar projects in the future, provide a reference basis. Retaining structure of deep horizontal displacement monitoring is one of the most important project of foundation pit safety monitoring, but in the process of the construction inevitably dip tube damage, prevented retaining structure displacement monitoring. From theoretical analysis, this paper proves that the reflection plate made with total station can be for remediation monitoring of deep horizontal displacement of retaining structures.
