摘要
在分析测小角法应用于特定方向上位移监测中存在的问题的基础上,提出了一种基于测站观测的方向距离法;通过对影响位移精度的有关因素进行分析,指出了使用该方法在方案精度设计时应注意的问题;针对基准点可能发生变动的实际情况,给出了具体观测和处理方法。
The method of surveying small angle can be implemented the specific direction displacement measurement. But in practice it is difficult for the users to realize displacement monitoring such as foundation pit and side slope etc. In this paper,after discussing the problems of small angle method,a new method of the displacement measurement based on measuring the direction and distance of the station point is presented.Through analyzing the relevant factors of affecting displacement accuracy in using this method,the announcements in the precision design are pointed out. Furthermore,because of the moving possibility of the reference point,the feasible methods of observation and data processing are provided.
