| Abstract: | In order to avoid the appearance of water inflow and guarantee the safety during the tunnels, mechanical behaviors of the highway tunnel constructed in the Karst areas are analyzed construction of with finite ele- ment method（FEM） under different hydraulic pressures and thicknesses between cavern and tunnel. The research results show that hydraulic pressure and wall thickness are two key factors to the water inflow during highway tunnels construction in Karst areas. |
