Abstract: This paper introduced the application of high-density resistivity survey method and seismic CT in geological investigation, which includes underground geology and aquifers, feature of space between surface and collapse in the tunnel and geological structure in front of the excavation works. Then, by data processing and analysis, the geological structure can be explained, for the repair of tunnel lining.

摘要： 介绍了采取高密度电法、地震CT 两种物探方法分别对隧洞区域地表以下地质情况和含水情况、地表至隧洞之间塌方体的空间形态以及开挖的前方工程地质结构进行综合勘察，然后根据对数据的处理和分析解释得出地质结构情况，得出物探结论，为隧洞衬砌修复提供科学依据。
