体外、体内预应力混合配筋结构与节段预制拼装施工工艺相结合的解决方案具有广阔的发展前景,这种结构施工工艺简单、施工迅速、耐久性好,克服了一般后张预应力混凝土工艺复杂、耐久性差的缺点。结合凫洲大桥引桥工程(普通后张法施工的连续梁)进行对比分析。 In vitro and in vivo prestressed hybrid reinforcement structure and segment prefabricated assembly process combined with the solution has broad prospects for the development of this structure is simple, rapid construction and durability, to overcome the general post-tensioned prestressed concrete technology Complex, poor durability shortcomings. Combining with the bridge approach project of Weizhou Bridge (continuous beam constructed by ordinary post-tensioning method), comparative analysis is made.
