主　　题：Tunnel Groundwater Water inrush Runoff 

摘      要：In tunnel construction,groundwater is often dried up,and vegetation around the tunnel is exhausted due to excessive water *** on the requirement of environmental sustainable development,it is of great practical significance to carry out in-depth research on this *** Jiupansi Tunnel crossing Xichang-Shangri-La Expressway as an example,on the basis of engineering geological investigation,the types of groundwater flow are studied,and the ways of groundwater discharge and recharge are ***,the surface runoff,underground catchment and water inflow caused by the construction are *** results show that during the construction period of the tunnel,the maximum water inflow is 6041 m 3/d,and the normal water inflow is 2041 m 3/d;the groundwater level is lowered,and the maximum influence radius of the funnel is 157 *** the point of view of groundwater and ecological environment impact,it is reasonable and feasible to construct tunnels under the condition of strengthening advance prediction,which will not cause larger groundwater environmental problems and have less impact on nearby residents and upper ecology.
