城市轨道交通施工技术发展与展望

以城市轨道交通建设领域桥梁与隧道工程施工技术的发展情况为基础,介绍了城市轨道交通节段梁预制及架设、跨坐式单轨曲梁现浇、U型梁预制及架设,以及隧道浅埋暗挖、盾构法、拱盖法、过海地铁钻爆法施工等技术的应用情况。阐述了复杂环境条件下未来城市轨道交通建设在城市轨道交通隧道施工、装配式车站及围护结构施工、BIM(建筑信息模型)技术应用等领域需面对和解决的新问题。

Development of Urban Rail Transit Construction Technol-ogy and Prospect

Based on the development of bridge and tunnel en-gineering technologies in urban rail transit foundation construc-tion,the application of current technologies are introduced in this paper,such as the segment prefabrication and erection, cast-in-situ concrete straddle monorail curved beam,U-shaped beam prefabrication and erection, as well as the tunnel shallow excavation,shield,arch covering,drilling and blasting method in seabed crossing project. Also,problems must be faced and solved in the future are elaborated,including urban rail transit tunnel construction, assembly station and surround-ing structure,and the application of BIM (building information modeling)technology in complicated working conditions.
