摘　　要：针对新建高铁线路引入既有车站,导致接发车股道有效长缩短的工程难点,结合实际案例对车站的信号布置进行优化研究,提出延长站台并设置防护区段、延长站台不设置防护区段和不延长站台优化车载系统等3种解决方案。从列车运行安全、土建工程可实施性等角度进行分析对比,可为在不同特定条件下,存在到发线有效长缩短、接车条件困难时的既有车站改造工程提供参考。In response to the engineering difficulties of introducing existing stations into the new high-speed railway line,which leads to the effective length shortening of the receiving-departure tracks,optimization research is conducted on the signal layout of the station based on practical cases.Three solutions are proposed,including setting protection section under the condition of extending platform,extending platform without setting protection section,and optimizing on-board system without extending platform.Based on the comparative analysis of the train operation safety and feasibility of civil construction engineering,the research conclusion provides reference solutions for the existing station reconstruction projects under different specific conditions such as effective length of the receiving-departure track is shortened and receiving train in difficult situation.
