The bridge is an artificial engineering structure and has the processes of construction, operation, maintenance and quitting use, the design service life of the large bridge in the highway is generally 50 years and 100 years, and the design service life of the railway bridge is 100 years. The actual situation is that a great part of bridges are required to be dismantled and newly built before the design service life due to structural defects, insufficient durability, long-term overload, outdated function, accident damage and the like of the bridges. It is expected that at the present stage, bridges crossing existing traffic lines will be dismantled and rebuilt in 30-50 years or even shorter time. The bridge dismantling project is a continuation of the bridge project and is a project with high danger. The removal of the bridge above the busy traffic line, particularly the railway traffic, needs to pay more attention to the traffic line, so that the transportation safety of the traffic line below the bridge is ensured, and the influence time on the traffic below the bridge is reduced as much as possible. The existing bridge dismantling work is divided into an in-situ dismantling method and an ex-situ dismantling method according to the relation with a designed bridge position. At present, the heterotopic removal method applied in China is constructed by adopting a top pushing method, and the construction method is pushed back when a bridge is removed.
