| 摘 要： | 超前地质预报是隧道施工中不可或缺的必要步骤,是降低施工过程地质灾害发生、减少灾害损失的重要手段.三维地震波层析成像技术是利用地震波反射原理,采用地震层析成像及全息岩土成像技术的新型超前地质预报技术,在国内应用较少.文中介绍了三维地震波层析成像技术的工作原理及方法,并结合工程地质类比法,对新建大瑞铁路尖山岭隧道进行了超前地质预报.研究结果表明,三维地震波层析成像技术对隧道超前地质预报效果良好,准确率达到90%.

| Abstract: | The geological predication is indispensable to minimize geological disaster before tunnel excavation. The 3D seismic wave＇s tomography, using seismic waves reflection principle and rock-soil mass vision 3D TM technology, rarely used in China, is a new kind of geological predication method. The operation principle and theory of the system is introduced, and its application to the tunneling in Jian Shanling Mountain for Dali-Ruili railway is discussed with engineering geological analogy. It is found that the 3D seismic wave＇ s tomography technology for tunneling＇ s geological predication is of good practicability and accuracy. |
