摘　　要：文章针对城市山岭隧道的特点,根据工程地质与水文地质条件,提出了地下水渗流计算边界条件假定,建立了符合城市山岭隧道工程特征的地下水渗流计算模型,在不同工况下进行了数值模拟计算,得到了城市山岭隧道地下水渗流的一般规律,并依据此特征规律分析了隧道防排水设计要点,最后给出了一套适用于城市地铁山岭隧道的防排水设计方案,为今后此类工程提供了理论指导与方案参考。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.
