摘要
南京地铁二号线东延线高架上部结构采用了U形梁形式,它具有投资省、适应能力强、外形美观等特点,但对设计与施工也提出了较高的要求。文章在分析U形梁的结构与性能特点基础上,对U形梁的设计技术及施工工艺进行了全面、详细的介绍,并阐述了U形梁施工设计的创新点。
U-shaped beam has been adopted on the superstructure of the eastern extension overhead engineering of the No.2 metro line of Nanjing,which with the features of lower investment,better adaptability and attractive appearance,but it requires higher standards for the design and construction of engineering.Critical technology of design and construction of U-shaped beam was described,and the innovation of this project was also introduced.
