摘　　要：深圳机场卫星厅为粤港澳大湾区重要机场交通枢纽工程,屋盖设计采用建筑结构一体化的设计理念,结构方案充分考虑建筑构型需求,利用结构布置逻辑与建筑设计逻辑一致的原则,以建筑平面X形构型为基准并结合室内X形装饰效果,最终屋盖结构体系采用交叉立体桁架结构方案。4个角部指廊屋盖结构为交叉立体桁架方案,2个中央指廊采用交叉立体桁架与三角锥网架混合结构方案,整个卫星厅屋盖交叉桁架最大跨度为75m,三角锥网架最大跨度为72m,从而结构方案实现了边界条件复杂情况下的大跨度空间效果。通过建立有限元模型进行各工况下的内力分析,对结构体系的静动力性能、结构稳定性、抗震性能及节点分析等关键技术进行阐述,并对交叉桁架与三角锥网架这类混合结构施工方案进行施工模拟分析。结果表明,屋盖结构体系采用交叉立体桁架方案不仅减少了传统桁架平面外需要设置侧向支撑需求,同时在结构逻辑布置上与建筑设计理念达到了融合,实现了建筑结构一体化的设计理念。Shenzhen Airport Satellite Hall is a crucial airport transportation hub in the Greater Bay Area of Guangdong,Hong Kong,and Macao.The roof design adopts an integrated architectural and structural design concept.The structural scheme takes into account the architectural configuration requirements and follows the principle of aligning structural layout logic with architectural design logic.The roof structure system ultimately employs a cross-linked three-dimensional truss structure,with the architectural layout based on an X-shaped configuration and combined with indoor X-shaped decorative elements.The roof structure of the hall consists of four main corridors oriented to the cardinal directions,utilizing a cross-linked three-dimensional truss scheme.The two central corridors employ a mixed structure scheme combining cross-linked three-dimensional trusses and triangular cone space frames.The maximum span of the cross-linked truss in the satellite hall roof is 75 meters,while the triangular cone space frame achieves a maximum span of 72 meters.This structural approach successfully achieves large-span spatial effects under complex boundary conditions.Through the establishment of finite element models for various load scenarios,the key technical aspects such as the static and dynamic performance,structural stability,seismic resistance,and node analysis of the structural system were elaborated.Furthermore,the construction simulation analysis of hybrid structures like the cross-linked trusses and triangular cone space frames was conducted.The results indicate that adopting the cross-linked three-dimensional truss scheme for the roof structure not only reduces the need for lateral support compared to traditional truss systems but also achieves integration with the architectural design philosophy in terms of structural layout logic,realizing the integrated architectural and structural design concepts.
