摘　　要：长珲铁路客运专线位于严寒地区,为确保隧道能够安全、快速、高质量的施工,必须采用冬期施工技术。本文根据以往施工经验,以长珲铁路隧道冬期施工为例,提出混凝土冬期施工方案,有效地解决了寒区隧道工程冬期施工过程中混凝土施工问题;在隧道洞口段和隧道洞内采取的防寒保温措施,改善了洞内作业环境,减少了隧道工程冬期施工成本。Chang Hui railway passenger transport special line is located in severe cold area. For ensuring the construction safety,fast and high quality,winter construction technology must be adopted. according to the former construction experience,a method of concrete construction in winter is presented and can availably solve the problems of concrete construction in the tunnels in cold regions; the measures of cold-proof and heat insulation is introduced in tunnel and portal of tunnel,to improve working environment and reduce construction cost.
