| 摘 要： | 在高地应力富水隧道开挖时，面临高压裂隙水突出的风险，对安全施工威胁很大。通过模拟掌子面前方裂隙水构造，使用多匝小线圈瞬变电磁法探测，能够较准确地探测出不同距离上的异常体位置。在实际应用中，采用多方向和多角度的三维数据采集技术，通过三维成果的立体显示对异常的分布能全面掌握，克服了传统瞬变电磁探测成果缺乏空间展布的弊端，解释成果有效、直观。

Application of Transient Electromagnetic Method in Advanced Detection of Tunnel Fissure Water |
| |
| Abstract: | During the excavation of the high-earth stress rich water tunnel, risk of high pressure fissure water, which poses a great threat to construction safety. By physically modeling the fissure water structure in front of the face and using the small wireframe transient electromagnetic method to detect, the abnormal body position at different distances can be detected more accurately. In the practical application, the multi-direction and multi-angle 3D data acquisition technology is adopted and the abnormal distribution can be fully mastered through the three-dimensional display of the 3D results, which overcomes the disadvantages of the traditional transient electromagnetic detection results that lack of spatial distribution and the interpretation results are effective and intuitive. |
