摘要
该文结合上海市闵行区浦江镇公共交通配套土建工程中U型梁后张法预应力张拉施工,针对U型梁的结构特点,对U型梁预应力张拉施工的工艺控制措施进行探讨,并提出了一些优化的张拉操作和应力控制的手段和方法。
Combined with the prestressing tensioning construction of U-type girder by the post-tensioning method in the civil construction project supported for Shanghai Minhang Pujiang Town Public Traffic and according to the structural characteristics of U-type girder,the article discusses the technological control measures of prestressing tensioning construction of U-type girder,and puts forward some optimized the means and methods of tensioning operation and stress control.
