水库是中国防洪广泛采用的工程措施之一,库区渗漏条件是建库主要的工程地质问题,直接影响水库效益的发挥。近年来,随着科技的发展,工程物探作为工程勘查的前沿学科发挥了越来越重要作用。在豫中某小型水库渗漏勘察中,成功应用了高密度电阻率法进行库区渗漏的勘探,较好的探测到影响库区渗漏的断层破碎带的分布情况。该方法成本低、效率高、适用性强,探测结果明晰,有很好的应用前景。 Reservoir is one of the widely used engineering measures in flood control in China. The seepage condition in the reservoir area is the major engineering geological problem of reservoir construction, which directly affects the reservoir efficiency. In recent years, with the development of science and technology, engineering geophysical exploration has played an increasingly important role as the frontier discipline of engineering exploration. In a small reservoir leakage investigation in Henan Province, the high density resistivity method was successfully applied for the exploration of reservoir seepage and better detected the distribution of the fault fracture zone that affected the seepage in the reservoir area. The method has the advantages of low cost, high efficiency, strong applicability, clear detection result and good application prospect.
