Research and Application on the Monitoring Technique of Slope Deformationabout Mountain Reservior

LIU Sheng;China Railway Si Yuan Survey and Design Group Co.,Ltd;  
The slope monitoring about mountain area reservoir is different from conventional deformation monitoring. It is affected by factors such as terrain, water level and environment. And as required, the expression of observation results will be different.This paper introduces the method of optimizing the control network using the free station, the method of acquiring elevation value of the monitoring points using intermediate trigonometric leveling instead of second order leveling. In addition, the method of enriching the expression forms of the monitoring results by the powerful mapping function of Arc Gis.
