高边坡挡墙变形监测方法探讨——全站仪自由设站差分法

Probing into the Method of Safe Monitor of High Slope——Difference Method with Total Station Actively

常用的高边坡监测方法是在高边坡周围设立固定的观测基站对高边坡进行监测,但高边坡变形会使观测基点产生位移,从而影响观测数据的准确性.为了避免高边坡变形对设立的固定观测基点的影响,提高观测精度,提出了全站仪自由设站坐标差分法的观测方法,论述了该方法的原理、误差分析以及其在高边坡变形监测中的应用.对在特殊环境下的变形观测有一定的指导意义.

The most common used method of safe monitor of high slope is to set a fixed observed point on which we can monitor the transformation. But the transformation of high slope may have an impact to the fixed point and the result which we take from the point may not be correct. To avoid the impact and improve accuracy, this article puts forward a coordinate difference-method to monitor the transformation of high slope with Total Station actively and expounes its principle,adjust ment calculation, error analysis and the application in the safe monitor of high slope. It may be constructive to the safe monitor in some special environment.
