利用现浇支架法施工预应力混凝土刚构桥技术

The Construction Technique of Prestressed Concrete (PC) Rigid- frame Bridge by Using the Cast- in- situ Support

结合二跨津塘公路刚构桥施工实例,详细介绍了采用满堂支架现浇法施工预应力混凝土刚构桥的技术、主要施工步骤和施工注意事项,指出其最大特点是改传统的利用挂篮进行悬壁浇注施工为满堂支架现浇法施工,是一种经济安全的施工方法。

Connecting with the actual example of the construction of the two- span rigid- frame bridge of Jing- Tang Superhighway, this paper introduces in detail the construction technique of PC rigid- frame bridge by using the raft cast- in- situ support, expounds the main construction procedures and the matters needing attention in the construction, and points out that this construction method is economic and reliable one comparing with the traditional cantilever casting method.
