既有铁路抢修钢梁通车性能分析

为保障铁路高效安全的运行,并最大程度的发挥既有抢修钢梁的潜力,对既有抢修钢梁按照现行新的规范和列车运行状态进行重新计算,并对结果进行分析研究。既有铁路抢修钢梁的设计荷载、限速要求、受力变形情况等指标难以适应现代铁路发展趋势。应利用新的理论和新的手段去分析钢梁特性,以设计出符合现代铁路需求、满足平战要求的新型铁路抢修钢梁。

Analysis of the Drive-Through Performance of the Existing Railways Rush-Repaired with Rush-Repair Steel Girders

To ensure the efficient and safe operation of the railway and to give full play to the potentiality of the existing rush-repair steel girders,new calculations are made of the existing steel girders for rush-repair according to the new railway norms and the new operation conditions of the present train in the paper,the results of which are analyzed and studied,for the data of the design loads,the requirements in speed limits and the deformation conditions of the existing rush-repair steel girders can not meet the needs of the development of modern railways.As a result,the characteristics of the existing rush-repair steel girders should be analyzed in the light of new theories and by new methods to design new railway rush-repair steel girders that meet the needs of modern railways and the requirements for railways in both wartime and peacetime.
