大地电磁法在水利工程深部断层调查中的应用探讨

Study on the Application of Magnetotelluric Method to Detect Deep Fault in Hydraulic Engineering

结合实际工程阐述大地电磁在测试断层位置、埋深、走向中的应用,并提出大地电磁法在应用中存在浅部地层分辨率低、测试电阻率为卡尼亚电阻率、不同模式下测试成果有差异等问题。采用该设备解决水利工程中的深部地质构造,减少重型设备投入大的不利因素,具有一定的应用市场,值得研究推广。

The paper introduces the application of the magnetotelluric method in the test fault location,the buried depth and the trend,and puts forward the problems such as the low resolution of the shallow strata in the application,the resistivity of the test,and the resistivity of the test and the difference of the test results in different modes.The device solves the deep geological structure in the water conservancy project,reduces the adverse condition of the heavy equipment investment,has a certain application market,and is worthy of research and popularization.
