Analysis on Water Pressure&Lining Structure Optimization of Underground Rail Transit Tunnel in Karst Area
Aiming at the high water pressure underground excavation of rail transit station tunnels in mountainous Karst cities,on the basis of summarizing the waterproof and drainage types of mining tunnels in China,the water pressure distribution characteristics and water pressure calculation methods of lining structure are mainly discussed,in order to give consideration to the protection of surface ecological environment and the optimization of tunnel lining structure design.Taking an urban rail transit station as an engineering example,it calculates&analyzes the mechanical properties of the lining structure corresponding to the full plugging tunnel and the plugging&drainage combination tunnel.The research results can provide references for the design of similar tunnel projects.
