摘要
近年来随着悬臂浇筑预应力混凝土连续梁桥在我国快速发展,对设计和施工各方面提出了很高的要求。文中根据多座预应力连续梁悬臂浇筑施工的实践经验,总结了悬臂浇筑临时锚固、合龙段施工及线形控制等方面的关键技术。
In the recent years,the cast-in-place cantilever method for the construction of the prestressed concrete continuous bridge has been rapidly developed in our country,which put forward very high requirements for many aspects of the design and construction.According to the practical experiences for the construction of many prestressed concrete continuous bridges,the key technologies such as the temporary anchorage,closure segment construction and line shape control are all reviewed in the present study,which c...
