摘　　要：广深港高速铁路是内地与香港地区跨境基础设施建设的重大项目。为了满足广深港高速铁路(香港段)建设需求,基于欧洲标准,对轨道线路上实现列车转线运行的重要设备——直向通过速度200 km/h的可动心轨辙叉单开道岔进行了设计,对道岔平面线型、结构部件、扣件系统、刚度均匀化等关键技术进行了研究,并进行了动力学分析和刚度均匀化设计,为符合欧洲标准道岔的设计提供了参考。Guangzhou-Shenzhen-Hong Kong high-speed railway is a major project of cross-border infrastructure construction between the mainland and Hong Kong region.In order to meet the construction of Guangzhou-Shenzhen-Hong Kong high-speed railway(Hong Kong Section),based on the European standards,the important equipment for train switching on the track-the single turnout with movable point crossing on the 200 km/h straight line,is designed.The key technologies of turnout geometry,structural components,fastening system and stiffness homogenization are studied,and the dynamic analysis and stiffness homogenization design are conducted,which provide references for the design of turnout conforming to the European standards.
