摘要
根据旧桥加固加宽的方法和设计施工特点,以现役预应力混凝土空心板桥的加固加宽为例,介绍采用碳纤维片材加固桥梁的施工工艺,并重点论述桥梁加宽所涉及的新旧盖梁连接、新旧空心板连接、新旧桥面铺装连接以及加宽部分预压等工作内容的设计要点和施工工艺,以期为类似工程提供借鉴。
In accordance with characteristic of Widening＆ strengthening methods and construction design of existing bridges, and taking existing prestressed concrete hollow slab bridges on active duty for examples, this paper introduces bridge - strengthening construction technology by using of carbon fiber sheets. Besides, it also mainly discusses design points and construction technologies such as connections between old bent caps and new ones, old hollow slabs and new involved in bridge widening, in hope of providing references for similar projects.
