Abstract：It is certain that tunnel construction can bring great impacts on the hydrogeological environment in karst areas.Taking the Huangniya tunnel project in Nanchuan district of Chongqing as an example,this pa-per uses ground investigation,tracer tests,long-sight monitoring and numerical simulation to analyze the in-fluence of tunnel engineering on the hydrogeological environment.The results show that the Huangniya tun-nel project has changed the groundwater flow field in the tunnel area,drained the groundwater,exacerbated drought and water shortage,and led to a new artificial water point-tunnel of gushing water.At the same time,the tunnel project destroyed the water resource allocation pattern and reduced the utilization rate of wa-ter resources.
