Exploring geological conditions for tunnel construction in hydropower engineering using a 3D resistivity method
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.
