【摘要】 本文介绍了城市轨道交通数字选线系统的开发成果以及开发过程中所解决的关键技术问题。中国的城镇化引起了城市人口与交通需求的增加,城市轨道交通的设计与建设得到迅速发展。然而,已有的城市轨道交通线路设计软件不能满足使用要求,存在许多问题。为了解决上述问题,中铁第一勘察设计院集团有限公司与中南大学合作研制了城市轨道交通数字选线系统。本文的第一部分是关于实际的开发结果,也涉及特定功能介绍,例如快速构建三角网数模、平面线形模型、喇叭口设计和坡度线实体的定制等。第二部分着重介绍开发期间解决的关键技术问题,包括:构建DTM的理论与方法、平面线形模型的构建、方案的自由组合与管理、线路几何图形与数据的双向驱动、不同车站类型的设计、单元法与模块法组合进行辅助线设计等。最后,本文介绍了城市轨道交通数字选线系统的应用情况。结果表明,该系统的开发是成功的,它将大大改进城市轨道交通线路设计的质量、效益与水平,产生明显的经济效益与社会效益。更多还原

【Abstract】 The paper will introduce the actual development achievements and the key technical problems solving during developing process of the "Digital Line Selection System of Urban Rail Transit(URT)".Chinese urbanization leads to increases in urban population and transportation demand.The URT construction and design was developed rapidly.However,existed URT design software cannot satisfy the using requirement which causes many problems.Digital Line Selection System of URT was born to solve the existing problems by China Railway First Survey and Design Institute Group Ltd.The first part of this paper is about the actual achievements of development,the specific functions are mentioned as well,such as rapid construction with triangular grid DTM algorithm,the plane linear model,the interactive design of the "bell mouth".custom of the grade line entity and so on.The second part focuses on the key technical problems solving during developing process.It begins with DTM theory and method,and then makes the plane general linear model.Next is management and free combination of line schemes and the mutual drive of geometry graph and the design data of the line.It also researchs for the station position design function of multi station type,the auxiliary line design method of unit and module combination and so on.Finally,this paper introduces the application of this system.The results show that the development of this system is successful,and it will greatly improve the quality,efficiency and level of URT line designing,resulting in significant economic and social benefits.更多还原
