摘　　要：文章以石家庄市中华大街上跨石家庄西环铁路(65+65)m无后浇段转体T构桥设计为背景,针对设计中面临的转体T构接收墩距离铁路过近的问题,研究采用一种无后浇段转体T构桥的结构体系。介绍了无后浇段转体桥上部、下部结构的设计要点,对转体系统设计及结构体系的计算进行了说明,总结了无后浇段转体结构设计的主要思路及计算方法。分析结果表明,在不同荷载组合下,该桥受力满足规范要求,转体系统布置合理,设计技术参数满足施工控制要求。Based on the design of the(65+65)m non-post-pouring swivel T-structure bridge across Shijiazhuang West Ring Railway on Zhonghua Street in Shijiazhuang City,this paper studies the structural system of a non-post-pouring swivel T-structure bridge in view of the problem that the swivel T-structure receiving pier is too close to the railway in the design.It introduces the design points of the upper and lower structures of the swivel bridge without post-pouring section,explains the design of the swivel system and the calculation of the structural system,and summarizes main ideas and calculation methods of the design of the swivel structure without post-pouring section.The analysis results show that under different load combinations,the force of the bridge meets the requirements of the specification,the arrangement of the swivel system is reasonable,and the design technical parameters meet the requirements of construction control.
