摘　　要：以成都至都江堰铁路设计为例,在遵循现行设计铁路规范的基础上,根据工程现场实际,否定了延长有效长、布置在路基上的安全线常规设计方案。通过分析安全线功能及轨道、车挡(含挡车器)、桥梁等设计要素,提出并实践了站场高架桥上安全线的设计方案:安全线高架桥梁两侧设防撞墙,在安全线末端组合设置滑动挡车器和固定挡车器,相应的桥梁荷载根据挡车器参数进行设计。满足了站场高架桥上安全线设计的要求。In accordance with existing railway design regulation and the actuality of engineering, this paper gives a negative attitude to such common safety siding design proposal as elongation of valid length and arrangement at subgrade for the Chengdu-Dujiangyan Railway. Through analyzing of function of safety siding on the viaduct and such design elements as track, bumper post （ including stop buffer） and bridge, the design proposal of safety siding on viaduct in the station and yard has been put forward and practised as follows ： anti-crash wall shall be set at both sides of safety siding viaduct ; both of movable and fixed stop buffer shall be set together at the end of safety siding; relative bridge load shall be designed in accordance with parameter of stop buffer. This paper can also be reference and guidance for design of safety siding on viaduct in the station and yard.
