摘要
横锦水库是一座以防洪、灌溉为主的大(2)型水利工程,水库除险加固后发现右岸测压管水位仍然很高,影响工程的正常运行。从测压管所处的工程地质条件、水文地质条件、观测资料等方面入手,分析得出测压管水位异常是由于放空洞局部洞段围岩破碎,放空洞充水承压时,内水沿工作缝及砼裂缝渗漏所造成的。
The Hengjin reservoir is a large 2 type hydraulic engineering,which main function is flood control and irrigation.After reinforcement,it is found that the piezometric level is still high at right bank of the dam,which has a bad influence on the normal operation of the engineering.The causes of the high level are analyzed according to the engineering geological condition,hydrogeological condition and observational data.It is due to the water leakages along construction joint and concrete crack when the emptying tunnel is full of water.
