| Abstract: | 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. |
