【摘要】：改革开放以来，我国交通运输业的迅速发展，使得我国铁路的路网空间密度和运输密度迅速增加，而自然灾害对铁路运输影响的可能性也随之增长，造成的损失亦趋于严重。而在所有的自然灾害中，暴雨洪水又是对铁路影响最大的灾害之一，也是我们需要重点关注的灾害,因此当务之急是要做好汛期前的各项防洪准备工作。本文首先对京九线137#桥抗洪能力及京广线沙河特大钢梁桥抗洪能力计算，检定两桥的实际防洪能力,结果表明两者桥梁都具有较强的防洪能力。其次为减少洪水对桥墩及桥下路基的危害，提出修建U型槽的设计方案。通过一系列对京九线137#桥和京广线沙河特大钢梁桥所在地的工况采集，结合相关施工技术标准及施工方法的研究，，确定最终实施方案。
[Abstract]:Since the reform and opening up, the rapid development of China's transportation industry has made the railway network spatial density and transport density increase rapidly, and the possibility of natural disasters affecting railway transportation has also increased. And of all the natural disasters, rainstorms and floods are one of the disasters that have the greatest impact on railways, and they are disasters that we need to focus on. Therefore, the urgent task is to do a good job of flood-control preparations before the flood season. In this paper, first of all, the flood control capacity of the 137# bridge in the Beijing-Kowloon Line and the anti-flood capacity of the Shahe super steel beam bridge in the Beijing-Guangzhou Line are calculated, and the actual flood control capacity of the two bridges is verified. The results show that both bridges have strong flood control capacity, and the second is to reduce the damage of flood to piers and subgrade. This paper puts forward the design scheme of building U-shaped groove, through a series of collection of the working conditions of the site of the 137# Bridge of Beijing-Kowloon Line and the Shahe Super large Steel Beam Bridge on the Beijing-Guangzhou Line, and combining with the study of the relevant construction technical standards and construction methods, the final implementation scheme is determined.
