阿尔及利亚阿奥铁路中邻河路堤冲刷防护设计及计算研究

Design and Calculation of Algiers—Oran Railway Embankment against Scouring

针对阿奥铁路(阿尔及尔—奥兰)中邻河路堤,按监理要求采用抛石措施进行防护。为此,对比了中阿两国铁路冲刷防护措施适用条件的差异,分析抛石冲刷防护设计中的水流速度与防护抛石粒径的关系,以及不同冲刷深度计算方法的区别。结合RBT 78008工点的冲刷防护设计,给出抛石冲刷防护的设计流程。

For the embankment of Algiers--Oran Railway near river, as required by the supervisor, riprap protection was used. For this purpose, the difference between the applicable conditions of scouring protection measures for the railways in China and Algeria was compared and, with regard to the design of riprap protection against scouring, the relation between the water velocity and the diameter of riprap was analyzed with the difference between the methods calculating the scouring depth. Combined with the souring protection design on the site of RBT 78008, the design process of riprap protection against scouring was put forward.
