摘　　要：港区工程中的闸口因功能要求和造型限制,多为大跨度空间结构。作为大跨度空间结构的一种,空间网架结构因跨度大、质量轻、稳定性好、施工快、造型美观等优点而在建筑结构领域得到广泛运用。针对闸口屋盖形式采用空间网架结构是否合适,依托实际工程案例,采用3D3S软件分别对钢结构网架屋盖的挠度、应力比、稳定性进行分析,阐述网架结构应用于闸口屋盖的受力特点和结构设计。结果表明,空间网架结构形式具有较高的安全度,工程设计可满足规范要求。研究成果可为进一步评价该类结构的可靠性及类似工程设计提供依据。The gates in port engineering are mostly large-span spatial structures due to functional requirements and shape limitations.As a type of large-span spatial structure,the spatial grid structure is widely used in the field of building structures due to its advantages such as large-span,light weight,good stability,fast construction,and beautiful appearance.Based on the actual engineering case,3D3S softwareis used to analyze the deflection,stress ratio and stability of steel structure grid roof,and the stress characteristics and structural design of grid structure applied to gate roof are expounded.The results show that the space grid structure has a high degree of safety,and the engineering design can meet the requirements of the specifications.The research results can provide a basis for further evaluating the reliability of such structures and similar engineering designs.
