先张法预应力混凝土简支“U”形薄壁结构梁施工工艺探究

Exploration of the Pre-tensioned Priestesses Concrete Simply Supported Thin “U” Beam Construction Technology

随着城市轨道交通的发展，安全、经济、环保的先张法预应力轨道梁开始大量应用。本文结合上海轨道16号线轨道交通高架 U 梁的技术特点，以及笔者多年的施工经验、技术成果，研究、开发出了本工程“U”形梁施工工艺技术方案。

With the development of urban rail transit, The safe, economical, environmental pretension priestesses rail beam has been widely used. Based on the technical characteristics of the elevated U beam of the line 16 of metro rail in Shanghai and his construction experience and technical achievements, the author developed the scheme in which the“U” shaped beam construction technology was applied in the project.
