解析寒区隧道二衬混凝土冬季施工温控技术

Analysis of Two Lining Temperature Control Technology of Concrete Construction in Winter Cold Regions Tunnel

寒区隧道二衬混凝土在冬季施工时,如果没有采取有效的温控措施,存在低温水泥水分不均匀、不充分的情况,则容易导致表面出现贯穿性裂缝、强度不达标等问题,严重情况下,还会影响隧道施工的质量和安全。以某隧道工程为例,研究了寒气隧道二衬混凝土冬季施工温控技术,以期为类似工程的提供一定的参考。

In the winter construction of concrete two lining of tunnel in cold region, if not take effective measures to control the temperature, low temperature cement water uneven, inadequate circumstance, can easily lead to problems through crack, strength is not up to the standard surface, in severe cases, will affect the quality and safety of the tunnel construction. Taking a tunnel project as an example, studied cold tunnel two lining temperature control technology of concrete construction in winter, in order to provide a reference for similar engineering.
