The Design of Super-wide Overweight Swivel T-structure Bridge Without Post-pouring Section
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.
