Abstract
Reservoir dam leakage detection is essential to operate and reinforce water conservancy projects safely.It is sig-nificant to ensure the safe operation of DAMS and the safety of downstream people's lives and property.According to the res-ervoir dam analysis's physical characteristics,this paper fully uses the advantages of the direct current method,which is very sensitive to apparent resistivity response characteristics for leakage channels.Therefore,the mise-a-la-masse and high-density resistivity methods are reasonably selected for comprehensive detection of the reservoir dam.Firstly,the mise-a-la-masse meth-od is used to pursue the leakage channel of the dam body and then combined with the high-density resistivity method for inter-preting the two-dimensional longitudinal profile of each line.Finally,through mutual verification of these two methods,the loca-tion and scale of potential leakage hazards are delineated effectively,and reliable results are obtained.So as to achieve the com-prehensive detection effect of point to line,line to plane,and provide an accurate and reliable basis for the investigation and rein-forcement of the seepage channel of the reservoir dam.关键词
