Research on Monitoring Method for 3-Dimensional Deformation of Earth Rockfill Dam
The routine methods for monitoring deformation of surface of earth rockfill dam has several defectives, i. e., slow measurement speed, heavy workload, monitoring information can not share with automation system. High precision total station system (TCA2003) can provide solution for research and development of 3-dimensional automation measuring technology of earth rockfill dam, however, atmosphere refraction and other issues affect the measuring precision. In accordance with actual condition of Yanshan Reservoir, the paper analyzes the refraction coefficient, raises that grey relation modification model of atmosphere refraction. As per the actual engineering instance, it can be seen that the model can modify triangle elevation measuring value, afterwards that vertical displacement value can meet precision requirement on safety monitoring of earth rockfill dam.
