在隧道(洞)的施工过程中,由于未能提前获知工作面前方的准确地质情况,在遭遇断层、溶洞、软弱破碎带等不良地质时,不能及时有效的应对,往往会造成经济损失和工期延误。本文研究了TRT6000超前地质预报系统在某公路隧道中的工程应用情况,通过预报结果、初勘资料以及开挖揭露情况的对比研究,分析了TRT在隧道(洞)超前地质预报工作中的探测效果:该方法能够较准确的预报出工作面前方的岩性变化区域,值得在隧道(洞)断层等不良地质预报中进一步推广。
In the tunnel (tunnel) construction process, due to the failure to know in advance the exact geological conditions in front of the face, encountered faults, caves, weak broken belt and other adverse geological conditions, the timely and effective response, often resulting in economic losses and duration Delay. In this paper, the engineering application of TRT6000 advanced geologic forecasting system in a highway tunnel is studied. Through the comparative study of forecast results, initial survey data and excavation revelation, the detection effect of TRT in advanced geological forecasting of tunnels (tunnels) is analyzed : This method can predict more accurately the lithology change area in front of working face and is worth to be further popularized in adverse geological prediction such as tunnel (hole) fault.
