Research on Groundwater Discharge Limitation in Mountain Tunnels in Strong Rich Water Areas Based on Ecological Protection
When the mountain tunnel passes through the strong water-rich area,the water content of the upper part of the tunnel and the surrounding stratum is often greatly reduced due to improper drainage methods,which adversely affects the ecological environment around the tunnel.Relying on the Gudoushan Tunnel Project,this paper carries out the technical research of water blocking and discharge restriction based on ecological protection,uses the method of calculating the volume of the drainage funnel,calculates the water inflow of the tunnel according to the Qiu Buyi model and the Taisi formula,and estimates the amount of water replenishment,and proposes the allowable discharge of groundwater suitable for tunnels in water-rich areas.
