摘要
文章简述了在复杂地形条件下、在隧道施工前和过程中,为了规避施工风险和预防施工过程中可能出现的地质灾害,运用瞬变电磁法勘察含水(泥)的断层、岩溶等水文地质问题;探讨了瞬变电磁法的理论基础、野外工作方法及资料处理。研究表明,瞬变电磁法勘探与其它常规电法相比,有许多突出的优点,可在复杂地形条件下工作,有良好的空间分辨性。实例中对瞬变电磁法勘察原理、工程实践和勘察效果作了详细介绍。
This paper describes the application of transient electromagnetic prediction of water-soaked faults and karsts etc. in complex mountain conditions of tunnel construction for avoiding construction risks and the prevention of possible emergence of geology disaster. The theoretic basis of TEM, its field implementation, data processing and interpreting are introduced. By contrast with routine electrical measurement methods, the transient electromagnetic technique possesses special advantages in space resolution under conditions of complex terrain. The principle of transient electromagnetic method in survey practice and corresponding results are introduced in detail.
