可控源音频大地电磁法在岩溶塌陷勘察中的应用

Application of controlled source audio frequency magnetotelluric method in karst collapse investigation

强岩溶发育区域往往是由于自然因素导致的,人为因素也会造成这种现象,并出现断层的问题。对于这样的区域进行判断,采用可控源音频大地电磁法是非常有效的。但是,如果存在地下隐伏岩,并已经出现溶塌陷,在对这样的位置进行判断的时候,就要结合使用其他的物探方法,还可以探测出溶塌陷负担埋深、所形成的规模以及其中的充填物性质等等。本论文着重于研究可控源音频大地电磁法在岩溶塌陷勘察中的应用。

Strong karst development area is often caused by natural factors,and human factors can also cause this phenomenon,and fault problems appear.It is very effective to use CSAMT to judge such areas.However,if there is underground hidden rock and karst collapse has occurred,it is necessary to use other geophysical prospecting methods to determine such location,and also to detect the buried depth of collapse burden,the scale formed and the nature of filling materials.This paper focuses on the application of CSAMT in karst collapse investigation.
