摘　　要：岩溶是铁路、高速公路等基础设施建设的地质隐患。岩溶与周围围岩存在密度,介电常数,波速等物性差异,使得可以用地球物理方法来对其进行探测。本文介绍了在宜万铁路齐岳山隧道平导右边墙上用地震映像法进行隧道岩溶的探测情况,取得了较好的地质效果。研究表明地震映像方法是一种高效快捷的物探方法,不仅可用于铁路公路隧道隧底的岩溶勘察,也可用于隧道边墙外的岩溶勘察。Karst cave is one of the typical natural hazard for the construction such as super- highway and railway. The difference of physical properties such as density, wave velocity and electrical conductivity between karst caves and their surrounding rocks, which makes the geophysical method be used for the exploration of karst caves. This paper introduces the applications of the seismic imaging method for exploring the karst cave beside the right side wall along Qiyueshan Tunnel. The study shows that the seismic imaging method can be used for exploring the karst cave not only under the bottom of tunnel, hut also beside the side wall of tunnel.
