江垭水利枢纽大坝运行监测与安全评估

Operation Monitoring and Safety Evaluation of Jiangya Water Conservancy Hub Dam

以江垭大坝(碾压混凝土重力坝)安全监测实测资料为基础,通过对大坝变形、渗流、应力应变和温度的分析,对江垭大坝安全运行进行了综合性评价。由于江垭大坝特殊的地质结构,出现了坝区和坝基抬升的现象,经研究分析和坝区抬升监测,抬升量是有限的,其它运行状态符合一般大坝运行特征。

on the basis of safety monitoring the measured data of Jiangya Dam （RCC gravity dam）, the safety operation of Jiangya Dam is comprehensively evaluated through analysis of darn deformation, seepage, stress, strain and temperature. Uplifting phenomena of the dam zone and the dam foundation were generated due to special geological structure of Jiangya Dam, the uplifting quantity is limited according to research and analysis, and dam uplifting monitoring, and other operation state accords with usual dam operation characteristics.
