摘　　要：寒区公路隧道受地质条件和水文环境的影响,在运营期间不可避免地出现渗漏水结冰等病害。因此,以京藏高速公路甘肃兰海段的大红山隧道和胡洼山隧道为工程背景,研究了病害处治技术,并对隧道在运营期间产生的二次衬砌开裂、渗漏水结冰、底板鼓起等病害原因,通过雷达扫描和钻孔取芯法等检测手段进行了分析,给出了相应的处治方案,在采取处治技术后病害得到了有效控制,未再影响隧道的正常运营。该处治技术可为相似寒区公路隧道的病害治理提供一定的参考。Due to the influence of geological conditions and hydrological environment,highway tunnels in cold regions inevitably experience diseases such as water leakage and freezing during operation.Therefore,based on the engineering of the Dahongshan Tunnel and Huwashan Tunnel in the Lanhai section of the Gansu section of the Beijing Tibet Expressway,disease treatment techniques were studied.The causes of secondary lining cracking,leakage water freezing,and bottom plate bulging during the operation period of the tunnel were analyzed by radar scanning and drilling core method.The corresponding treatment plans were provided.After adopting treatment techniques,the diseases were effectively controlled and no longer affecting the normal operation of the tunnel.This treatment technology can provide a certain reference for the disease treatment of tunnels in similar cold regions.
