Application of High-density Electrical Method and Microkinetic Spectral Ratio Method in Leakage Detection of Shiwangou Reservoir in Qingdao
In this paper,Shiwangou Reservoir in Qingdao City is taken as the research object.High-density electrical method and microtremor spectral ratio method are used to jointly detect the dam body in the southeast of the reservoir.By analyzing the"distortion phenomenon"of the high-low resistance conversion and the small spectrum ratio area of the high-low spectrum ratio conversion,the location and scale of leakage are found,and the permeability path is estimated to be a trend of about 354° and a width of about 20 m.After verification by drilling,the results show that the joint detection has achieved good results,which provides a reliable basis for the reservoir's later anti-seepage treatment.
