摘　　要：查清岩溶地区长隧洞的岩溶水文地质条件,对工程的顺利实施及保护施工人员的生命安全有着至关重要的作用。以绿塘水库输水隧洞为例,笔者阐述了EH4电导率成像系统的原理,对EH4探测结果进行分析,并结合水文地质调查和钻探,查明隧洞岩溶的特征、规模、发育规律。经隧洞开挖表明,现场揭露的岩溶分布情况与EH4探测结果基本一致,说明EH4探测方法在隧洞岩溶勘察中效果较好,有明显的应用价值和指导作用,为类似工程岩溶勘察提供借鉴。Finding out the karst hydrogeological conditions of long tunnels in karst areas plays a vital role in thesmooth implementation of the project and the protection of the life safety of the construction personnel.Takingthe water conveyance tunnel of Lvtang Reservoir as an example the authors expound the principle of EH4 conductivity imaging system analyze the detection results of EH4 and find out the characteristics scale anddevelopment law of tunnel karst in combination with hydrogeological investigation and drilling.The tunnelexcavation shows that the karst distribution revealed in the field is basically consistent with the EH4 detectionresults indicating that the EH4 detection method has good effect in tunnel karst exploration and has obviousapplication value and guiding role which provides reference for karst exploration of similar projects.
