六盘山复杂地质条件下的隧道超前地质预报技术

Advanced geological prediction of geologic hazard for Liupanshan tunnel under complicated geological conditions

以六盘山复杂地质条件下的隧道开挖超前地质预报技术为研究对象,采用以TSP203为主的超前地质预报系统进行了研究应用,减少了隧道开挖时地质灾害情况的发生,大大地提高了掘进速度,保证了工期,提高了经济效益。通过TSP203在六盘山复杂地质条件下的现场试验,证明了TSP203隧道超前地质预报系统能够在复杂地质情况下取得良好的超前预报效果。

Through studying advanced geological prediction for the Liupanshan Tunnel under complicated geological conditions,mainly adopting the TSP203 System,the geological disasters in the process of tunnel excavation were greatly reduced,the tunneling speed was greatly raised,the time limit for the project was guaranteed,and the economic benefit was increased.The field test carried out at the Liupanshan Tunnel with the TSP203 System under complicated geological conditions has proved that the prediction system can achieve better advanced prediction effects than the former methods under complicated geological conditions.
