摘　　要：针对我国高速铁路桥梁的发展及目前我国普通铁路桥梁抢修技术储备方面的现状,分析总结了未来遭受灾害损毁的高铁桥梁,在进行应急抢修及快速恢复时,所面临的技术问题和难点,例如新制混凝土箱梁的建造、灾后桥墩的恢复以及新制梁体的换架施工等等;由于不同的工况、毁损部位和施工的难易程度等,应本着预有准备、多案并举、安全快速和因地制宜的原则实施受损桥梁抢修与恢复。有助于推动我国高速铁路桥梁灾后应急保障技术的发展。With the development of the high-speed railway bridges and the present situation of the technical reserve in rush-repairing common railway bridges in our country taken into account,analyzed and summed up in the paper are the technical problems and difficulties such as the construction of new concrete box girders,the recovery of the post-disaster bridge piers and the replacement and erection of the new beams,which might be faced with when rush-repairing and quick recovery are performed after high-speed railway bridges are damaged or destroyed.Considering different working conditions,different damaged locations,and the difference in the degrees of construction difficulty,various construction schemes should be prepared in advance and different construction plans for the same case should be got ready simultaneously in order to perform the rush-repair and quick recovery of damaged bridges in the principle of safety,quickness and suiting the construction schemes to local conditions.The paper may help promote the development of China＇s post-disaster rush-repairing support technology for high-speed railway bridges.
