深基坑水平位移监测有关问题的探讨

Research on Monitoring of Horizontal Displacement in Deep Foundation Pit

在深基坑变形监测中,位移是反映基坑变形最直接的物理量,而且安全预报的准确性在很大程度上取决于位移数据的准确性,因此获得准确反应基坑变形的位移数据尤为重要。基于此,详细介绍了围护桩顶位移监测的方法与精度分析以及测站点偏移量计算的简易方法。

In the deformation monitoring of a deep pit, the horizontal displacement is the most direct parameter which reflects the deformation of a deep pit. Furthermore, the accuracy of safety predicting depends on the accuracy of displacement data at a large extent. Therefore, the data getting appears to be much more important. For this purpose, this paper introduces in detail the supporting pile top displacement monitoring precision analysis and the simple calculation method of the side-play mount calculation of the station points.
