站踞塬谷 桥路融城——“四合”理念下的西安东站方案设计

The Station Is Located in the Loess Valley;the Bridge and the Road Merge into the City:Design of Xi’an East Railway Station Under the Concept of“Four Harmonies”

西安东站是西安市规划高铁、普铁、城际、地铁、公交一体的特大型枢纽站,针对设计中面临的城市视觉通廊控制、城市与自然多层次融合、城市交通复合网络以及分期建设与形体控制等问题,采用“塬谷复合、杜白缝合、站城融合、桥路结合”的“四合”理念,结合特殊的城市区位、地理环境及交通条件,重点分析建筑功能分区与流线组织的关系,进而从平面布置、形体组合与立面设计等方面提出了设计要点与策略,并应用软件模拟验证了室内外光环境和风环境的舒适性。

Xi’an East Railway Station is a mega hub station of Xi’an with the planning of high-speed railway,ordinary railway,intercity railway,underground,and bus.In view of the problems faced in the design,such as the control of urban visual corridor,the integration of city and nature at multiple levels,the composite network of urban traffic,and the phased construction and shape control,the“Four Harmonies”concept of“Loess and Valley Composite,Dubai Sewing,Integration of Station and City,and Combination of Bridges and Roads”has been adopted to analyze the relationship between the functional zoning of the building and the streamline organization in the context of the special urban location,geographic environment,and traffic conditions,put forward the design key points and strategies in terms of the plane layout,the combination of shapes,the elevation design,etc.,and verify the comfort of indoor and outdoor light and wind environments by applying the software simulation.
