摘要
在岩溶地区单一的预报方法难以全面准确地预测不良地质情况。通过比较TSP、地质雷达、瞬变电磁、红外探测及超前钻探等隧道超前地质预报方法的各自特点,结合贵广铁路GGTJ-1标斗篷山隧道超前地质预报工作,介绍了上述各自超前地质预报手段在实际工程中的运用,针对岩溶地质预报总结出简便有效的TSP、地质雷达和超前钻孔3种预报方法,并最终形成岩溶地区综合超前地质预报技术。
A single geological prediction method is hard to find unfavorable geological body comprehensively and accurately in karst area.Comparing with kinds of advance geological prediction methods in tunnel,which are TSP,georadar,transient electromagnetic method,infrared detection and advance exploration drilling,etc,in combination with the advance geology forecast of Doupengshan Tunnel of bid section GGTJ-1 in Guiyang-Guangzhou Railway,aiming at tunnel geological prediction in kast area,the paper sums up three convenient and effective forecast methods(TSP,georadar,advance exploration drilling) and eventually forms the comprehensive advance geological prediction in karst area.
