| 摘 要： | 断层破碎带的出现必然使岩体的硬度发生明显改善,而瑞利波的传播速度恰与介质的物理力学特性有关。利用瑞利波探测技术,对泉三高速公路某施工隧道含水大断层进行超前探测,并与地质雷达和钻探探测结果比较,结果显示,锐利波探测的断层破碎带宽度与隧道施工揭露的极其吻合,瑞利波是超前预报含水断层破碎带的一种简便、高效的技术。

| Abstract: | The occurrence of fault belt must change the hardness of rock mass.The translation speed of Rayleigh wave is related to physical and mechanical properies of medium.The Rayleigh wave survey technique is used for water-bearing fault belt pre-pretection in the process of a tunnel construction of Quansan highway,and the result is compared with the result of ground penetracting radar.It is indicated that the Rayleigh wave technique is a kind of simple,effective technique for pre-detecting water-bearing fault belt in the process of the tunnel construction. |
