摘　　要：提出新时期铁路桥梁抢修技术研究应突出“两个快速性”的观点,即提高抢修钢桥拼组架设的速度和行车速度。分析了当前既有架设技术的速度水平和各种钢梁的限速情况,提出了提高拼架速度和行车速度的技术构想和相关措施。The idea that the study of rush repair of railway bridges during the new period should have its greater stress placed on the ＂two accelerations＂ is put forward in the paper, by which the author means that both the assembling and erecting speed of steel girders for rush repairs, and the running speed of the train should be accelerated. With the existing technical levels of erecting operations and the speed limits for different types of steel girders analyzed, some technical propositions related to the acceleration of the assembling and erecting speed, and that of the running speed of trains, as well as corresponding measures, are suggested.

关 键 词：铁路桥梁 抢修钢梁 快速性 拼组架设 行车速度
