为解决跨东北地区年度冬季施工这一技术难题，以哈尔滨地铁烟厂站为例，在理论研究的基础上，对冬季地铁施工的冬季保温措施进行分析，阐述了在高寒地区地铁车站保温施工的方法。提出了钢结构屋顶配珍珠岩加车站内升温的方法，有效解决了地铁车站进行冬季施工的难题，实践证明此方法是有效的，科学的。

The winter of northeast China, usually last from November to March of next year, is bitter cold. And the period between the middle of December and early February of next year is the coldest time, with average temperature below -15 ℃, average highest temperature below -9 ℃ and average lowest temperature below -20 ℃. In order to solve the problems of metro station construction in winter of northeast China, the construction of Yanchang metro station of Harbin metro is studied through theory research, heat preservation measures analysis of metro station construction in winter and construction methods introduction of heat preservation of metro station in bitter cold area. Then, an innovative method is proposed to tackle the problem of metro station construction in winter that is steel roof with perlite and calefaction in metro station. The application of this method shows that it is effective and scientific.
