浅谈北隈子隧道水害处理

Brief Discussion on Beiweizi Tunnel Flood Damage Treatment

公路隧道在冰冻期低温条件下,易遭受冻害影响,危及行车安全。结合丹本线北隈子隧道在发生可溶盐结晶堵塞中心水沟部分过水断面,并遭遇极端低温条件,使隧道排水系统堵塞,形成水害、冻害,在该工程背景条件下,探讨公路隧道水害的处理方法及工程防治措施,以期能为今后公路隧道勘察设计、施工及营运管理提供借鉴。

Highway tunnel is inclined to be influenced by freezing damage and endanger the traffic safety under low temperature condition in frost period. Combine the situation occurred to Dandong- Benxi highway Beiweizi tunnel that soluble salt blocked center ditch caused the water surpass the section and it is exposed to extreme low temperature conditions that jammed the drainage system of the tunnel which leads to flood damage and freezing damage. Under the background of that engineering project,highway tunnel flood damage treatment method and engineering control measures has been discussed to provide reference for future highway tunnel survey,design,construction and operation management.
