摘　　要：港珠澳大桥珠海口岸位于人工填岛上,针对其特殊的环境,介绍了珠港旅检楼钢屋盖体系的确定过程,提出需重视钢结构防腐、金属屋面抗风等内容。分析结果表明,支撑钢屋盖的局部关键柱破坏引起屋盖的局部破坏,未引起连续性倒塌,但局部破坏的影响仍较大,设计应对可能受到攻击的部位采取加强措施。大跨结构设计中应根据屋盖分块提升施工方案进行施工模拟分析,并基于施工成形状态进行正常使用阶段的设计复核,确保施工及使用阶段结构的安全。Zhuhai Port of Hong Kong-Zhuhai-Macao Bridge is located at a man-made island.Due to its unique surrounding environment,this paper introduces the steel roof system of the passenger inspection building,the anti-corrosion treatment of steel structures,and the wind resistance of the metallic roof.Based on the result of progressive collapse analysis of the steel roof,local failure of some critical columns causes only local damage of the roof structure.Due to the great influence of local damage,strengthening measures are needed at those places where attack may happen.Construction simulations are necessary according to different lifting construction schemes of steel roof in the design of long-span structures.In order to confirm the security of the structure during its service stage,the simulations and the load capacity verification are required based on the serviceability limit state.
