根据承重构件种类及性能的不同,预应力混凝土桥可分为简支桥、连续桥、铰式连续桥、V撑连续桥等几种,本文将某大桥作为研究对象,其根本性质为预应力混凝土连续刚构大桥。有关数据表明该桥在多年运行之后出现了桥面破损、超车道防滑层脱落、桥梁裂缝等建筑病害,为了更好的研究其加固的施工过程,本文从某大桥的病害现象以及出现病害的原因出发,而后对桥梁的加固过程、加固工艺、监测过程等进行了详细的阐述,望对今后我国桥梁建筑以及桥梁加固工艺的的发展起到一定的促进作用。
According to the different types and performance of load-bearing members, prestressed concrete bridges can be divided into several kinds, such as simply supported bridges, continuous bridges, hinged continuous bridges and continuous V-bridges. In this paper, a bridge is taken as the research object, Concrete continuous rigid frame bridge. Relevant data show that after years of operation of the bridge, there appeared bridge decks, shedding of anti-skid layers in super-lanes and building cracks in bridges. In order to better study the reinforcement construction process, this paper analyzed the disease phenomenon and the causes of the diseases Then it elaborates the process of reinforcement, the reinforcement process and the monitoring process of the bridge in detail. It is expected to play a certain role in promoting the development of bridge construction and bridge reinforcement in our country in the future.
