大地电磁测深法在水利水电地质勘察中的应用

Application of Magnetotelluric Sounding Method in Geological Exploration of Water Conservancy and Hydropower

鉴于常规槽探、硐探、井探、钻探技术在现代工程地质勘察应用中周期长、耗费大、精度低等问题,文中以大地电磁测深法为论述对象,以水利水电工程为依托,通过滑坡勘探、深厚覆盖层勘探和隐伏断层勘探工程实例的应用证明,该技术实施效果良好,与有限的槽探、硐探等技术资料形成互补,获取的地质信息更加丰富和精准。

In view of the problems such as long period,high cost and low accuracy of conventional trenching,adit exploration,well exploration and drilling technology in the application of modern engineering geological exploration,this paper takes magnetotelluric sounding as the object of discussion,and takes water conservancy and hydropower projects as the basis,and through the application of landslide exploration,deep overburden exploration and hidden fault exploration engineering examples,it is proved that the implementation effect of this technology is good,and with limited trenching The technical data such as adit exploration are complementary,making the geological information obtained more abundant and accurate.
