TSP203系统在岩溶隧道探测中的应用研究
|
摘要
岩溶地区隧道施工常遇到溶洞、暗河、断层、突水、突泥等地质灾害,给施工带来了重大隐患。为了保证岩溶地区隧道施工安全,需对岩溶的发育情况进行超前预报。基于TSP203超前地质预报系统,对吉茶高速公路麻栗场隧道出口右洞进行超前预报,对比溶洞实际开挖情况,分析了该系统的实用性、可行性,以及在指导施工方面中的作用。结果表明,与其他预报方法相比,TSP系统在准确性、预报距离和操作可行性等方面优势显著。
The geological disaster such as karst fault,underground river,water and slurry gushes often happens in karst area during construction of a tunnel,which brings momentous disaster to construction.The advanced geology prediction about the development of karst is very important to protect the security of tunnel construction.In this paper,TSP203 system is used to forecast the cave in right inlet of Malichang tunnel.In contrast with the actual excavation of cave,the practicality,feasibility and important role of this system to construction is analyzed.The results show that TSP advanced geological forecast system has more advantage than other methods in preciseness,forecasted distance and operation feasibility.
