摘要
重庆西站主体结构为混凝土结构,上部结构为钢结构。站房屋盖主结构采用正交空间管桁架结构体系,跨度大、矢高高;无站台柱雨篷位于高架站房南北两侧对称布置,采用清水预应力混凝土结构。基于本工程结构施工难度大、安装困难、施工组织管理难度高的特点,详细介绍其施工组织部署及预应力关键技术等。
The main structure of Chongqing West Railway Station is concrete structure and the superstructure is steel structure.The main structure of the station building is orthogonal space tube truss system with large span and high vector.Awning without column is arranged symmetrically on the north and south sides of the elevated station house.Based on the characteristics of the construction difficulty,installation difficulty and construction organization and management difficulty of this project structure,this paper introduces the construction organization and deployment and key construction technologies of prestress in detail.
