摘　　要：对哈尔滨市典型公路隧道涎流冰病害案例进行总结,分析冰体发育过程中的水源及渗流通道。通过实地勘察与计算模型相结合的方法,针对水源的渗流情况以及隧道所受冻胀力作用影响展开研究。结果表明,地表水和地下水的渗流为涎流冰发育过程提供物质基础,结构表面和内部的裂缝为水源提供渗流通道。天然因素和人为因素在特殊情况下会改变渗流量的大小,是造成隧道涎流冰病害的重要因素。另外,裂隙间的水分在低温条件下发生冻结,向外施加压力产生冻胀力作用,扩大原有裂缝,导致隧道冻害更加严重。The case of salivary flow ice disease of typical highway tunnels in Harbin city was summarized,and the water source and seepage channel during the development of ice body were analyzed.Through the method of field investigation and calculation model,the seepage of water source and the influence of frost heaving force on the tunnel are studied.The results show that the seepage of surface water and underground water provide the material basis for the development process of salivary flow ice,and the cracks on the surface and inside the structure provide the seepage channels for the water source.Natural factors and human factors will change the size of seepage flow under special circumstances,which is an important factor causing salivation ice disease in tunnel.In addition,the water between the cracks freezes at low temperature,exerting pressure outward to produce frost heaving force,enlarging the original cracks,leading to more serious freezing damage in the tunnel.
