Abstract:Because of its special geographical location and climate conditions, the Antarctica constructional engineering has unique characteristics. The advantages and disadvantages of the two structural schemes of the independent steel frame structure and the attached gallery structure were compared. The gallery structure scheme was more in line with the characteristics of the Antarctica constructional engineering due to its fewer processes, shorter construction period and stronger wind resistance. It was finally determined as the structural scheme of the vegetable production greenhouse project in Antarctic Zhongshan Station. According to the meteorological data and standard formula of Antarctic Zhongshan Station, the wind load value of Antarctic Zhongshan Station is 1.6kN/m2. The dimensions of the main structural members of the project and the reinforcement measures for the local members of the original structure were introduced, and the matters needing attention in the Antarctica construction of the project were briefly described. The gallery scheme and reasonable value of wind load adopted in the project not only made the project construction economic and safe, but also simplified the construction process and shortened the construction period, which had certain reference significance for the reconstruction and expansion of the existing buildings of the Antarctica scientific research station in the future.

Keywords:Antarctica Zhongshan Station; gallery structure; independent steel frame structure; wind load
