［摘要］濟(jì)青高鐵青島紅島站為全高架橋建合一的鐵路樞紐站房，由站房和站臺(tái)雨棚組成，其中站房面積約7萬(wàn)m2，雨棚覆蓋面積約4萬(wàn)m2。主站房最大平面尺寸為268m×310m，為地上2層(局部3層)大跨框架結(jié)構(gòu)，站臺(tái)層及其以下為鋼筋混凝土結(jié)構(gòu)，站臺(tái)層以上為鋼結(jié)構(gòu)。站房承軌層采用橋建合一的結(jié)構(gòu)體系，結(jié)構(gòu)形式為普通鋼筋混凝土梁+鋼骨混凝土柱；高架候車層采用“鋼管混凝土柱+大跨度鋼桁架+鋼次梁”結(jié)構(gòu)，減輕了樓蓋結(jié)構(gòu)自重，有利于在結(jié)構(gòu)高度范圍內(nèi)布置設(shè)備管線；鋼屋蓋采用雙向空間管桁架結(jié)構(gòu)。南北入口處浪花造型結(jié)構(gòu)形式采用空間網(wǎng)格鋼結(jié)構(gòu)。對(duì)主站房結(jié)構(gòu)進(jìn)行了結(jié)構(gòu)靜力分析、振型分解反應(yīng)譜法分析、動(dòng)力彈塑性時(shí)程分析和樓蓋舒適度分析等。詳細(xì)結(jié)構(gòu)分析表明，紅島站結(jié)構(gòu)體系傳力明確，結(jié)構(gòu)安全、可靠，同時(shí)具有良好的經(jīng)濟(jì)性和美觀性。

Abstract:The Qingdao Hongdao Railway Station of  Jinan-Qingdao High-speed Railway is a railway hub station building with bridge-station combined structure. It consists of a station building and a platform canopy. The station area is about 70 000 m2, and the canopy covers  area is about 40 000 m2. The maximum plane size of the main station building is 268m×310m. It is a two-story (partially three-story) large-span frame structure above the ground. The platform layer and below are reinforced concrete structures, and the layer above the platform is a steel structure. The rail-bearing layer of the station building adopts a bridge-station combined structure system. The structural form is ordinary reinforced concrete beam and combined steel and concrete column; the elevated waiting layer adopts the structure of concrete steel tube column, large-span steel truss and steel secondary beam, which reduces the self-weight of the floor structure to facilitate the arrangement of equipment pipelines within the height of the structure; the steel roof adopts a two-way space tube truss structure. The wave-shaped structure at the north and south entrance adopts a spatial grid steel structure. Structural static analysis, mode decomposition response spectrum analysis, dynamic elastoplastic time-history analysis and floor comfort analysis of the main station building  were carried out. Detailed structural analysis shows that the structural system of Hongdao Railway Station has clear force transmission, safe and reliable structure, and good economy and aesthetics.
