深基坑水平位移监测方法与精度浅析

Methods Analysis of Horizontal Displacement Monitoring of Deep Foundation Pit and Its Accuracy

在深基坑变形监测中,水平位移是反映基坑变形最直接的物理量,如何及时有效地获得准确反映基坑变形的位移数据尤为重要。监测研究以安徽省节水技术推广研究中心大楼基坑变形监测为例,使用高精度徕卡0.5″全站仪,采用棱镜强制对中的方法,对该深基坑的支护顶或坡体的特定方向进行水平位移监测。同时,对监测中工作基点和监测点布置方法、监测流程以及精度优化等进行了探讨,为后期相关工程的研究和实施提供参考。

In the deep excavation deformation monitoring, the horizontal displacement is the most direct reflection of pit deformation quantities, and how to get timely and effective displacement data accurately reflect the pit deformation is particularly important. Monitoring studies to promote water - saving technologies in Anhui Research Center building pit deformation monitoring, for example, the use of high - precision Leica 0.5 ＂ total station, using a prism forced on the method of deep foundation supporting the roof or the slope of the horizontal displacement monitoring specific direction while working basis for monitoring arrangement and method for monitoring points, monitoring processes, and precision optimization are discussed to provide a reference for the study and implementation of post - related projects.
