寒冷地区隧道冬期施工技术

Tunnels Construction Technology at Cold Region in Winter

朝阳隧道处于东北寒冷地区,气候条件极其恶劣。为保证整个工程的施工进度和工程质量,必须采取冬期施工。在以往工程的施工经验基础上,结合当地气候特点,在经过实际应用与科学研究基础上,优化了料仓保温实施方案,并提出了寒冷地区隧道施工混凝土配合比方案,即保证了隧道冬期施工的顺利进行,又为其他寒冷隧道施工提供参考。

Chaoyang tunnel locates in the northeast cold region where the weather conditions are extremely bad. In order to ensure the construction progress and quality of the whole project,winter construction must be taken. In the previous construction experience,combined with the local climate characteristics,based on the practical application and scientific research on the optimization of the heat preservation silo project,the cold area tunnel construction scheme of concrete mix proportion is put forward,which ensures the smooth construction of the tunnel in winter,and provides a reference for other cold tunnel construction.
