摘要
针对施工环境给水平位移监测中工作基点检测带来的困难,该文分析了后方交会仿权公式在不同图形中的运用及计算方法。通过工程实例介绍,将该方法应用于特定环境下水平位移工作基点的检测,取得了较高精度的观测成果。该方法对工作基点发生的位置变化可起到检测和改正的双重效果。
Aiming at the difficulties of working basic points monitoring in horizontal displacement caused by construction environment,the application and calculation method of gravity center formula by resection method in different graphics are analyzed.Through engineering examples,the method is applied in working basic points monitoring of horizontal displacement in special environment,and the observation results are obtained with higher precision.This method can not only detect but also amend the position change of working basic points.
