摘要(Abstract):

南极大陆因为其特殊的地理位置和气候条件,决定了南极建筑工程具有独特的特点。对独立钢框架结构和附建式连廊结构两种结构方案进行了优缺点对比,连廊结构方案因其工序更少,施工周期更短,抗风能力更强,因此更符合南极建筑工程的特点,最终确定为南极中山站蔬菜生产温室项目的结构方案。南极建筑主要控制荷载为风荷载,依据南极中山站的气象资料和规范公式,明确了南极中山站建筑的风荷载取值为1.6kN/m~2。介绍了项目主要结构构件尺寸和对原结构局部构件的加固措施,简述了南极施工中应注意的事项。项目采用连廊结构方案,且风荷载的取值合理,使得工程建设不仅经济、安全,而且建设工序简化,工期缩短,对将来南极科考站已有建筑的改扩建工程具有一定的借鉴意义。
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 1.6 kN/m~2. 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.
