摘要
为提高隧道施工过程中的岩溶预报的准确性,以及验证新设备在岩溶隧道超前地质预报工作中的应用效果,采用TSP603 系统在国内铁路岩溶隧道中开展超前地质预报应用工作,并给出数据采集和处理过程中的注意事项,然后将得到的成果图与超前水平钻结果进行综合预报分析,进而推断出掌子面前方存在3 处岩溶发育段落,结果表明,两种方法对岩溶发育位置的判断基本一致,后期开挖揭示验证,实际地质情况与预报结果基本吻合.研究表明,TSP603 系统作为一种新型超前地质预报设备,凭借其处理算法和多参数解译等优势,能够在一定程度上提高岩溶预报的准确性,可推广至类似岩溶隧道的超前地质预报工作,但仍需联合其他物探手段进一步验证其在溶洞及岩溶水等方面的预报效果.
Abstract
In order to improve the accuracy of karst prediction in tunnel construction and verify the application effect of new equipment in karst tunnel advance geological prediction,TSP603 system was applied in the advanced geological prediction of domestic railway karst tunnels.Some matters needing attention in the process of data collection and processing were given.The results obtained were combined with advanced horizontal drilling for comprehensive prediction analysis,it was inferred that there were 3 karst development sections in front of the palm.The results show that two methods are basically consistent in determining the development location of karst.Through later excavation and verification,the actual geological condition is basically consistent with the detection results.The research results indicate that the TSP603 system,as a new type of advanced geological prediction equipment,can improve the accuracy of karst prediction to a certain extent with its advantages of processing algorithm and multi-parameter interpretation,and can be extended to similar karst tunnel advanced geological prediction.However,it is still necessary to combine other geophysical methods to further verify the prediction effect of the system on karst caves and karst water.
