Application of ERT in Groundwater Exploration of Jinci Spring Reflow Project
The reflow of Jinci spring with important cultural and social values is of great sig-nificance to the construction of ecological civilization in Shanxi Province.Replacing groundw-ater with surface water source,building barrage at suitable location to store water and raise the water level can increase the infiltration and recharge of Jinci spring and advance the re-flow of Jinci spring.It is very important to determine the best site for dam construction and identify the relevant hydrogeological characteristics in shallow effectively with electricity re-sistivity tomography.Based on the previous geological survey results,four electricity resis-tivity tomography survey lines are laid in the main leakage section,and a series of results have been achieved,which can offer reference for the site selection of surface water recharge groundwater project.Based on the numerical simulation results,this paper concludes that the formation at L2 survey line of Longweitou has good vertical and lateral permeability,and it is more suitable for dam construction.
