典型工程变形监测的一种新方法及应用研究

Study on a New Method for Typical Deformation Monitoring Projects and Its Applications

摘要: 针对广州城市地铁、高支模工程和大型基坑变形监测实际，本文研究总结了一种基于测量机器人的变形监测新方法，即混合基点网法和多点强制自由设站边角交会法，并成功应用于多个典型工程。实践证明，该方法简单易行，自动化程度高，监测精度可满足多种典型工程的变形预警要求。

Abstract: According to the actual situation of high-formwork engineering and large deformation monitoring in Guangzhou subway, this paper studies the new method of monitoring based on measuring the deformation of a robot, that is a mixed base-point network method and multi-point & compulsory free-station linear-angular intersection method, and it was successfully applied to a number of typical projects. Practice has proved that the method is both simple with high degree automation. At the same time, monitoring accuracy can meet the requirements of a variety of typical deforma- tion warning works.
