综合物探在豫西某水库大坝坝体检测中的应用

The Application of Integrated Geophysical Prospecting in a Reservoir Dam in West Henan

水库的大坝渗漏隐患是一个十分严重且难以解决的问题。以豫西某水库的坝体检测为例,根据地球物理特点,采用高密度电法、自然电场法综合性的物探方法,探测坝体内的老灌溉洞和漏水点的位置。物探的探测结果,结合钻孔验证表明,综合性的物探方法在查找均一坝体的老灌溉洞和漏水点时,物性的差异明显,探测效果显著,为大坝的坝体加固和防渗漏提供了依据。

Reservoir dam leakage is a very serious and critical problem. Taking a reservoir dam detection in west Henan for example, the location of the old irrigation hole and water leakage in the dam were detected with the comprehensive method of high density resistivity and the natural electric field , according to the geophysical characteristics . The detection results of geophysical exploration, combined with the drilling verification showed that property difference was obvious and the detection effect was remarkable with the integrated geophysical method in detecting the location of old irrigation hole and water Leakage point, which can provide the basis for dam reinforcement and seepage prevention.
