CRTS Ⅱ型板式无砟轨道系统桥梁梁面施工缺陷处理方案研究

摘要

采用CRTSⅡ型板式无砟轨道系统的桥梁，对底座板施工前的梁面平整度和梁面标高等都有很高的要求，通过工程实例对几种常见梁面混凝土缺陷的处理，总结了几种处理措施、方法和实施过程中应该注意的事项，对以后的类似施工起到借鉴作用。%A bridge which adopts CRTS Ⅱ slab ballastless track has a higher standard for deck surface smoothness and elevation preciseness before track base plate is constructed. This article puts forward, through specific project cases, some measures and methods to deal with some common bridge deck construction defects. Some key points which must be followed to deal with these defects are also mentioned. It could be a reference to construction project of a similar nature.
