摘要
针对高寒地区隧道混凝土抗冻性等性-能的要求,采用实验的方式制备符合高寒地区隧道的混凝土,并将制备的混凝土结合温控技术应用到白拉山隧道二衬施工中。最后通过实践表明,本文制备的混凝土结合温控技术,能够满足高寒地区隧道施工中对抗冻融的要求,具有一定的工程实践的价值。
in view of the requirements of frost resistance of tunnel concrete in the high cold area,the concrete meet⁃ing the requirements of tunnel in high cold area is prepared by experiment,and the prepared concrete combined with temperature control technology is applied to the second lining construction of kalongla tunnel.Finally,the prac⁃tice shows that the concrete combined with temperature control technology prepared in this paper can meet the re⁃quirements of freezing and thawing resistance in tunnel construction in cold area,and has a certain value of engi⁃neering practice.
