摘要: 江西南石壁隧道地处岩溶发育区,运营期间每逢季节性强降雨便出现涌水涌泥病害,涌水点分散,涌水量大,多次治理未能彻底解决。精确定位水源及导水通道是病害治理的前提。在注浆治理前采用综合探测法进行探测,以瞬变电磁、高密度电法定位水体,以地震映像法发探溶洞及断层破碎区,综合多种物探结果比对分析,确定了不良地质体的空间位置及展布形态。通过左洞钻探揭露情况及注浆时的串浆路线,验证了物探结果的正确性。研究结果表明:对于运营中的岩溶区隧道,综合使用多种物探技术,相互印证,能够较为精确的定位充水溶洞以及导水裂隙的空间分布,对于隧道的病害处治施工具有指导意义。

Abstract: The Nanshibi Tunnel in Jiangxi province is located in the karst development zone. During the operation period, the water gushing and mud gushing diseases occur every time of seasonal heavy rainfall. The water gushing points are scattered and the water gushing volume is large, which cannot be completely solved by many treatments. Accurate positioning of water source and water guiding channel is the premise of disease control. The integrated detection method was used to detect before the grouting treatment. The water body was located by transient electromagnetic and high-density electric method, and the cave and fault-breaking area were detected by seismic mapping method. The comprehensive geophysical prospecting results were compared and analyzed to determine the spatial location and distribution pattern of the unfavorable geological bodies. The correctness of geophysical prospecting results was verified by the exposure of left hole drilling and grouting line. The research results show that: for operating tunnels in karst areas, the comprehensive use of multiple geophysical prospecting technologies and their mutual confirmation can accurately locate the spatial distribution of water-filled karst caves and water-conducting fissures, which is of guiding significance for the tunnel disease treatment construction.
