摘要： 本文以丹大快铁跨后盐特大桥等八座桥梁垫石防震落梁挡块病害整治施工为实例，详尽地论述了桥梁垫石、防震落梁挡块病害的成因，在既有线施工的重点及难点，施工封锁时间天窗点内有针性的整治方案，施工工艺流程及施工技术方法。积累了既有线桥梁垫石防震落梁挡块病害施工的相关经验，在确保运营线安全的前提下，完成诸多病害整治施工任务。
Abstract: This paper takes the construction of eight bridges such as the Dandong-Dalian Expressway Bridge and other eight bridges as examples, and discusses in detail the causes of the diseases of bridge cushions and earthquake-resistant falling beams. The key points and difficulties of the construction, the targeted rectification plan in the skylight point during the construction blockade time, the construction process flow and the construction technology method. It has accumulated relevant experience in the construction of existing bridge cushions against earthquakes and falling beams, and has completed many construction tasks of disease remediation on the premise of ensuring the safety of the operation line.
