摘要
广州内环线东山口立交中山一路西标段设计采用三跨预应力钢—混凝土结合梁结构 ,跨度布置 (5 0 + 70 + 6 0 )m ,高跨比为 1/32。简要介绍了该大跨度异形结合梁设计思路及分析计算方法 ,从中探讨了防止结合梁负弯矩区混凝土桥面板开裂的方法。
A structure of 3 span prestressed steel concrete compossite girder is adopted in the design of Dongshankou Grade Separation Project in the West Bid Section of No.1 Zhongshan Road. The depth span ratio is 1/32. In this paper, the design concept and method of analysis of large span steel concrete composite beam are introduced, and the method of avoiding cracking of the concrete deck slab is also illustrated.
