计算机辅助工程项目设计已是现代铁路规划建设的发展方向.首先阐述了国外铁路仿真软件的应用情况及在国内使用的局限性，接着介绍了客运专线大型客运站仿真系统的整体结构设计；然后分别说明了系统内各子系统的功能结构设计及相互连接关系.最后，以广州南站作为案例，通过设置车站的全天分时段分方向到发列车数与股道使用规则，仿真了高峰两小时车站的到发线、咽喉区段道岔占用情况以及相应的利用率统计情况，并对仿真结果进行了分析评价，说明了仿真软件的有效性.

Design and Application of Operation Simulation System for Large Terminal of Passenger Dedicated Line

Computer-aided engineering design is the future trend of modern railway planning and construction.This paper summarizes the application status of railway simulation systems at abroad and their limitations in China.The overall structural design of operation simulation system for large terminal of passenger dedicated line is introduced.The functional structure design and connected relation of each subsystem within the system are also presented.Then,taking the New Guangzhou Railway Station of China as an example,the study simulates the occupancy status of tracks and throat areas and obtains corresponding utilization statistics in two peak hours by different arriving and depicturing train numbers and tracks using rules in different time and directions during one day.The results are analyzed and evaluated to prove the validity of the simulation system.
