| Abstract: | Aiming at the problem that the ordinary leveling observation methods could not be implemented in subsidence monitoring,through the triangulation measurement principle and the analysis of error sources,the method of the implementation of the intermediate station-type precise trigonometric leveling in subsidence monitoring was studied in this paper,observational accuracy and feasibility were also analyzed.The experiments showed that this method could gain the subsidence data of the monitoring body more quickly and easily,meantime the efficiency of working could be raised,moreover,it could have the guiding significance and practical value in the subsidence monitoring in the complicated environment. |
