Study on the Impact of Tongluoshan Tunnel on Groundwater Environment Based on Hydrochemical Analysis

Abstract:

This study applies gray relation analysis method to make an estimate of the range that influenced by Tongluoshan tunnel construction on groundwater environment, using hydrochemical data of groundwater sampled from tunnel and wells as well as springs. Results calculated reveal that the gray relation grades varies from 0.48 to 0.89 with an average of 0.63 to 0.76, implying that the inflow from tunnel is closely related to the groundwater system which recharges the wells and springs. And an area about 3.5 square kilometers consists of rangeⅠand rangeⅡ, distributing mainly in the carbonate aquifer field around tunnel is inferred as the zone that might be influenced by Tongluoshan tunnel construction. So the wells and springs in these ranges may disappear if a good link existing between the tunnel and aquifers that recharges the wells and springs.
