Seepage Analysis and Design and Application of Waterproof and Drainage in Subway Mountain Tunnel
Based on the characteristics of urban mountain tunnels and the engineering geological and hydrogeological conditions,a boundary condition assumption for groundwater seepage calculation is proposed in this paper.A groundwater seepage calculation model that conforms to the engineering characteristics of urban mountain tunnels is established.Numerical simulation calculations are conducted under different working conditions,and the general law of groundwater seepage in urban mountain tunnels is obtained.Based on this characteristic law,the key points of tunnel waterproofing and drainage design are analyzed.Finally,a set of waterproof and drainage design schemes suitable for urban subway mountain tunnels is provided,providing theoretical guidance and scheme reference for such projects in the future.
