浅谈大截面大体积转换梁施工

针对某工程施工特点和难点，从混凝土浇筑方式的选择，分层浇筑方式支撑及回顶系统的计算，转换层总体施工顺序、构造措施和大体积混凝土施工等方面对其技术要求进行了探讨，指出采用分层浇筑法可以节约支撑成本、缩短工期，为类似工程提供参考借鉴。

On the construction of large section mass transfer beam

Aiming at the construction characters and difficulties of one project, it discusses its technical requests from the selection of concrete cast-in-place mode, support of the mode of cast-in-place by layer, the calculation of back tip system, the whole construction sequence of transfer layer, the constitution step and mass concrete construction, and points out that it can save the cost and shorten time of the project by adopting the method of cast-in-place by layer, and gives reference to the similar project.
