自由设站法在基坑水平位移监测中的应用

Application of Free-station Positioning to Deformation Monitoring of Foundation

介绍了自由设站法进行基坑水平位移监测的整个过程,通过在某一具体基坑监测中的应用,发现其不仅消除了目前常规基坑监测方法存在的诸如对中误差、视差等误差的影响,还避免了基准点稳定性的问题,精度满足规范要求,具有较好的工程实用价值。

The process of monitoring the deformation of foundation using the method of free-station is introduced.Through the application to a foundation,we find that the method not only eliminates the influence of aligning error and disparity,but also avoids the problem of the stability of benchmarks.
