Study on Joint Detection of Seepage Passage of Reservoir Dam
The leakage of reservoir dam is hidden and potentially harmful,which seriously threatens the safety and service life of reservoir dam,so it is necessary to adopt feasible detection technology for detection and treatment.Based on this,the combined detection technology of high-density electrical method and comprehensive tracer method is proposed to carry out high-density electrical method,temperature field tracer,water chemical element mass concentration tracer and tracer detection of reservoir leakage channels.The leakage path of reservoir dam is finally determined.The results show that the application of the combined detection technology can verify the results of high-density electrical detection with a variety of tracer tests,make reliable and accurate judgment of low-resistance abnormal areas,make unique interpretation of high-density electrical detection results,and provide a reliable basis for the reinforcement of the reservoir.
