引水隧洞施工过程中,破碎岩体、断层、含水溶洞、地下暗河等是常见的赋存灾害源的不良地质体,在开挖揭露或施工扰动的作用下,容易导致塌方、突水涌泥等地质灾害,传统的地球物理探测技术与仪器根本无法适用。采用三维地震波法探测方法在引水隧洞工程施工隧道中开展了实际的探测工作,通过实例验证其预报良好效果,三维地震波法探测是一种可以用在引水隧洞施工隧道中超前地质预报方法,具有广泛的应用前景。
In the process of diversion tunnel construction, crushed rock mass, fault, aqueduct and underground river are common geological bodies that are the source of disasters. Under the action of excavation revelation or construction disturbance, it is easy to cause landslide and water bursting And other geological disasters, the traditional geophysical detection technology and equipment simply can not apply. Three-dimensional seismic wave method is used to carry out the actual exploration work in the construction tunnel of diversion tunnel project, and the good results are verified by examples. The three-dimensional seismic wave method is an advanced geological prediction method which can be used in diversion tunnel construction tunnels, The application prospects.
