叠合预制预应力双T板的连接方法比较

Comparison of Connection Methods of Laminated Precast Prestressed Double T-shaped Plates

结合工程实际,对双T板的几种主要节点连接方式和施工方法进行了梳理和总结。通过对双T板的反拱、吊装和安装就位等施工工况进行有限元计算分析,为施工提供了建议,以确保施工的安全,并可为类似工程参考。

Combined with the engineering practice,several main joint connection modes and construction methods of double T-shaped plate are summarized.Through the finite element calculation and analysis of the construction conditions such as reverse arch,hoisting and installation in place of double-T-shaped plate,some suggestions are provided for the construction to ensure the safety of construction,and can be used as a reference for similar projects.
