综合直流电法勘查尾矿库区漏水通道效果

Effect of application of comprehensive direct current methods to survey of leaking passage of tailings bank

通过一个实际工程应用的例子,介绍了综合直流电法勘查地下漏水通道,并取得了良好的地质效果。特别是在勘查场地条件困难情况下,采用充电法、自然电场法等直流电法手段查明地下漏水通道位置、宽度以及下延深度等问题。基于充电法的工作原理,采用了一种新的观测方式,命名为电流强度法。

With an example from engineering application,this paper introduced comprehensive direct current methods that were applied to investigation of underground leaking passage produced good geological result.Especially in case of difficult site conditions,mise-a-la-masse method,self-potential method and other direct current methods were used to identify the location,width and downward extension of underground leaking passage.Based on the working principle of mise-a-la-masse method,a new observation method,called current intensity method,was adopted.
