摘　　要：为开展水电工程隧道施工地质条件的探查与研究,基于三维电阻率技术构建了隧道地质条件的计算模型,采用数值模拟获得隧道模型的三维电性分布特征;将该技术应用于云南某水资源配置工程现场探查,经钻孔验证,获得了良好的探查效果。研究结果表明三维电阻率法对水电工程隧道的施工地质条件探查具有好的适用性,能够准确判断地层层厚,圈定岩溶空洞的大小、位置及充填物性质。通过探测研究获得的定量、定性信息,为隧道施工管理、信息化建设和防灾提供了可靠的依据。To explore the geological conditions for the tunnel construction in hydropower engineering,this study built a calculation model for tunnel geological conditions using a 3D resistivity method.Through numerical simulations,this study determined the 3D re-sistivity distribution of the tunnel model.Then,the model was applied to the field exploration of a water resource allocation project in Yunnan,yielding satisfactory exploration results,as verified through drilling.The findings suggest that the 3D resistivity method can be effectively applied to the exploration of geological conditions for tunnel construction in hydropower engineering by accurately determining formation thicknesses,as well as the sizes,locations,and filling characteristics of karst cavities.The quantitative and qualitative data obtained from exploration in this study lay a reliable foundation for the management,informatization,and disaster prevention of tunnel construction.
