Abstract:

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.

Key words: metro station, bitter cold area of northeast china, steel structure, station construction in winter, heat preservation
