摘要
通过对U形梁、箱梁和T形梁3种梁型的几种常规跨度的简支梁进行综合比较分析,研究确定采用30 m U形梁作为本线高架桥区间的标准梁跨;通过对城市轨道交通常见的不同类型桥墩的分析比较,确定该线标准线间距高架桥墩采用单柱式T形标准桥墩,随着线间距加大,标准墩自然过渡到Y形墩;通过对深圳地铁6号线高架段桥梁总体设计研究和分析,结合该线高架桥5大集成创新技术,提出了城市轨道交通高架桥设计应注意的要点,并阐述了深圳地铁6号线跨立交、路口和河流等特殊梁桥设计原则、一般连续梁结构设计及大跨度预应力结构设计等内容,其设计理念及创新技术对后续城市轨道高架桥梁的建设具有重要借鉴意义.
In this paper,several conventional simply supported beams of U-beam,box beam and T-beam are comprehensively compared and analyzed,and the 30m U-beam is determined as the standard beam span of the viaduct section of the line. Through the analysis and comparison of different types of common piers in urban rail transit,the elevated pier with standard line spacing of this line adopts single column T-shaped standard pier. With the increase of line spacing,the standard pier will naturally transit to Y-shaped pier.The design principles of overpasses,intersections and river bridges,the design of general special continuous beams and the design of long-span prestressed structures are described respectively. Through the research and analysis of the overall design of the viaduct section of Shenzhen Metro Line 6,and combined with the five integrated innovative technologies of the viaduct of this line,this paper puts forward the key points that should be paid attention to in the design of urban rail transit viaduct. Its design concept and innovative technology have important reference significance for the construction of subsequent urban rail viaduct.
