摘要
简要介绍了 ５０ ｍ预应力槽型梁预制施工方案的选择、设计和施工等憎况。５０ｍ槽型梁是全国同类型桥梁中跨度最大的梁。其施工工艺复杂，而且安装难度大。但如果能正确选择预制施工方案，则可以减小施工难度和提高工效，确保工期提前完成，并能收到较好的经济效益。
The paper describes briefly the selection and design of the alternatives for 50m prestressed channel beam precasting, as well as its construction work, The span of the 50m prestressed channel beam is the largest among the same type of beams in our country, characterized by complicated construction techniques and difficulties in erection, But should the construction alternatives for precasting be chosen coffectly, the difficulties for construction could be minimized and the efficiency could be improved, so that we may have a shorter construction duration and better economic benefits,
