摘要
以青岛市石湾沟水库为研究对象,采用高密度电法和微动谱比法对该水库东南部坝体进行联合探测,通过分析其高低阻转换的“畸变现象”和高低谱比值转换的小谱比值区域,找到渗漏的位置和规模,推测其渗透路径为一条走向约354°、宽度约20 m的断裂构造带。钻孔验证结果表明联合探测取得了较好的效果,为该水库后期防渗处理提供了可靠依据。
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.
