［摘要］石家莊站是一座集鐵路、地鐵、城市道路交通換乘功能于一體的現(xiàn)代化大型交通樞紐工程。石家莊站以“拱橋”為表達主題，為建橋合一建筑。整個結構通過2道變形縫，自上而下分成3段，以減小東西向溫度區(qū)段長度。首層結構為軌道層，采用了預應力技術解決大跨混凝土梁承載列車荷載的問題，同時應滿足民用建筑和鐵路橋梁規(guī)范的設計要求。高架候車層為混凝土柱、預應力混凝土梁的框架結構，屋面結構為三角形立體鋼管桁架體系，通過6片箱形實腹鋼拱墻支承在高架候車層上。為平衡拱腳推力，拱下框架梁采用了直線預應力筋與曲線預應力筋相結合的方式。同時，拱腳框架柱采用型鋼混凝土柱，以提高結構的抗震性能。箱形實腹鋼拱墻的采用充分體現(xiàn)了結構和建筑形態(tài)、效果的完全統(tǒng)一。三維實體模型的整體分析及罕遇地震下的彈塑性分析表明，結構體系具有良好的抗震性能。

Abstract:Shijiazhuang Railway Station is a modern large traffic hub project which contains transfer functions of subway, railway and urban road traffic. Arch bridge is the subject of the station, and the project of Shijiazhuang Railway Station is a building-bridge combined structure. In order to reduce the length of temperature segment along the east to west, the structure is divided into 3 sections by 2 deformation joints. The first floor structure is the track layer where pre-stressing technique is used to solve the problems of large-span concrete beam bearing the train loads. Meanwhile it should also meet the design requirements of civil building and railway bridge codes. The elevated waiting layer adopts frame structure composed of pre-stressed concrete beam and reinforcement concrete column. The roof structure adopts the triangle spatial steel tube truss system that is supported upon the elevated waiting layer through six pieces of box-shaped and solid-web steel arch walls. In order to balance the huge push force of the arch foot, straight pre-stressed tendons and curve pre-stressed tendons are combined in the frame beam under the arch wall. The steel reinforced concrete columns are used in the frame column at the arch foot to develop seismic performance of the structure. The perfect combination of architecture effect and structure effect is realized by using box-shaped and solid-web steel arch wall. The overall analysis and the elastic-plastic analysis under the rare earthquake on the three-dimensional solid model indicate that the whole structural system has good seismic performance.
