| 摘 要： | 秦岭输水隧洞穿越秦岭岭脊，延伸长，埋深大，断裂构造发育，其对工程的设计和施工影响极大。采用可控源音频大地电磁法能有效探测隧洞深部地质构造特征，通过对探测结果与实际施工情况进行了对比分析研究，确定了区内36条断层的分布情况。研究结果表明可控源音频大地电磁法在查明隧洞深部地质构造形态特征及其赋水性方面效果良好，可在其它深埋长隧道断裂勘察中推广应用。

The Application Research of CSAMT Used in the Prospecting of the Fracture of Water-conveyance Tunnel of Qinling |
| |
| Abstract: | Water-conveyance Tunnel of Qinling Mountain which crossing the ridge of Qinling Mountain has many complicated geological conditions such as extending in far distance, buried deeply, developing fault structure extremely. These conditions have a considerable impact on the design and construction of the project. CSAMT is an effective way to probe the characteristics of geological structure in depth. The distribution of 36 faults has been confirmed by making a contrastive study on the probe''s results and the actual construction situation. The research shows that CSAMT has good effect on probing the morphological characteristics of geological structure in depth and the water content of the tunnel and this method can be extended and used in other prospecting of the fracture of the tunnel which extends length, buried in depth. |
