摘要
为提高超前地质预报的准确度,降低施工现场发生突发灾害的概率,研究了如何根据不同的工程特性选用更为有效的超前预报方法。比较探讨了TGP206和地质雷达两种超前预报方法的基本探测原理,依托马口排岩溶隧道ZK225+975~ZK225+875,K226+276~K226+251,ZK226+285~ZK226+260里程段为工程背景,介绍了TGP206和地质雷达探测马口排隧道掌子面未施工段围岩异常地质状况的现场工作原理和方法,将超前预报结果与实际施工中的情况对比,验证了两种超前地质预报准确性,并通过比较TGP206和地质雷达在马口排隧道超前地质预报中的优缺点。
In order to improve the accuracy of advanced geological forecast and reduce the probability of sudden disaster at construction site,the article studies how to choose more effective forecasting method according to different engineering characteristics. The basic detection principle of TGP206 and geologic radar is discussed. Based on the engineering background,the TGP206 and Geology are introduced according to the ZK225＋975~ZK225＋875 and K226＋276~K226＋251 mileage the accuracy of the accuracy of the two advanced geologic forecasts is verified by comparing the results of the advance forecast with the actual construction. The accuracy of the two advanced geologic forecasts is verified by the radar working conditions. By comparing the advantages and disadvantages of TGP206 and geological radar in the advance geological prediction of Maokoupai tunnel.
