测量不确定度分析方法在基坑水平位移监测中的应用

Horizontal Displacement Monitoring of Foundation Pit Using Measurement Uncertainty Analysis

把不确定度分析方法引入基坑水平位移监测领域,并从理论上分析了常用的两种水平位移监测方法(极坐标法和小角度法)的测量不确定度。文章结合工程实例进行计算分析,通过对不同水平位移监测方法的不确定度分析,得出了小角度法较极坐标法相比,精度更高。

In this paper,uncertainty analysis method is introduced into the field of horizontal displacement monitoring of foundation pit.Then,it theoretically analyses the measurement uncertainty of two horizontal displacement monitoring methods(polar coordinate method and small angle method),which are commonly used.This paper calculates and analyses with engineering examples.It analyses the uncertainty of different horizontal displacement monitoring methods.It concludes that,the small angle method is more accurate than the polar coordinate method.
