深步水水库运行监测分析及大坝安全性评估OA

A surface deformation and seepage monitoring system has been established to scientifically evaluate the safety status of the Shenbu Reservoir dam that has been in operation for over 60 years.Through the use of second-order leveling measurement,polar coordinate method,and vibrating string permeameter,this paper continuously observed and analyzed the settlement,horizontal displacement,and leakage of the dam body from May 2022 to December 2024.The results showed that during the monitoring period,the surface deformation of the dam(cumulative maximum settlement of 9.10mm,displacement of 7.1mm)tended to stabilize and no abnormalities were observed.However,the leakage of the dam body has shown an increasing trend year by year and is significantly correlated with the reservoir water level.
