综合超前地质预报技术在穿河隧道中的应用

Application of Integrated Advance Geology Forecast Technology in a River-crossing Tunnel

穿河隧道由于其特殊性,在施工中极易受到不良地质现象的影响,因此,施工前进行超前地质预报是十分必要的。通过对武广客运专线浏阳河隧道超前地质预报技术的研究,介绍综合超前地质预报技术在该隧道中的应用,重点分析TSP法与红外探水的应用效果,旨在依据实践总结两种方法的优点和缺点,并提出解决方案,使综合超前地质预报技术能更好地发挥作用。

Because of the frequent encountering of serious geological hazards during construction of river-crossing tunnels, pre-construction geology forecast is rather essential. Taking Liuyang River Crossing Tunnel on Wuhan-Guangzhou passenger-dedicated railway as an example, the authors present the application of the integrated advance geology forecast system in Liuyang River Crossing Tunnel in detail. Then, in order to summarize the advantages and disadvantages of these two methods from practice, they mainly analyze the effects of TSP and infrared water detectors. Subsequently, they put forward solutions to improve the effect of the integrated advance geology forecast system.
