Summary:The present invention relates to a railroad bridge reinforcement method using point displacement, pier reinforcement, and bridge upper structure continuation, for a construction method to make a discontinuous upper structure continuous for a railroad bridge constituted in a form with continuing simple piers, comprising: a first step to install a bracket on the top of the pier; a second step to install a new reinforcing material on each of the adjacent discontinuous upper structures and to move an existing support on the bracket corresponding to the new reinforcing material; a third step to make the adjacent discontinuous upper structure continuous after removing an existing reinforcing material of the adjacent discontinuous upper structure; and a fourth step to install a new support on the bottom of a continuation point of the discontinuous upper structure. The present invention provides sufficient resistance to a load in a longitudinal direction when a continuous welded rail is installed. 본 발명은 단순지간이 연속된 형태로 구성된 철도철도교량의 불연속 상부구조를 연속화하는 공법으로서, 교각의 상부에 브라켓을 설치하는 제1 단계; 이웃하는 상기 불연속 상부구조 각각에 신규 보강재를 설치하고, 상기 신규 보강재에 대응하여 상기 브라켓 상으로 기존 받침을 이동시키는 제2 단계; 이웃하는 상기 불연속 상부구조의 기존 보강재를 제거한 다음 이웃하는 상기 불연속 상부구조를 연속화하는 제3 단계; 및 상기 불연속 상부구조의 연속화된 지점 하부에 신규 받침을 설치하는 제4 단계를 포함하는 것을 특징으로 하는, 지점 이동, 교각 보강 및 교량 상부구조 연속화를 이용한 철도 교량 보강 방법에 관한 것이다.
