铁路隧道工程辅助设计系统的设计与实现

研究目的:在分析铁路工程隧道设计工作流程和特点的基础上,建立铁路工程CAD系统的整体架构,从复杂系统各组成部分统一协调的角度出发,把其中的各子系统看作既互相关联又互相独立的部分,结合辅助设计软件在行业内应用的深度、广度及复杂性等特点,建立各子系统的数学模型,采用面向对象的技术研发系统.研究结论:由于在铁路隧道工程辅助设计系统的研发过程中,坚持了以隧道设计业务需求为导向,以整体架构与局部模块相统一的逻辑模型,采用OOP分析技术,合理划分设计对象的粒度大小,保证了系统功能划分的合理性,有效地提高了开发效率.该系统完成后在多条铁路干线上进行应用,效果良好.系统还具有易于集成,易于维护的特点,为专业设计软件的研发提供了值得借鉴的解决方案.工程应用表明,系统技术架构和实现方法是可行的.

The Design and Practice of Railway Tunnel Engineering CAD System

Research purposes: The framework of railway tunnel engineer CAD system is built on the basis of analyzing the workflow and specialties of railway design,from a collaborative view of complex system with each sub-system which either independent or related to build their own mathematical models combine with the advantages of the depth,details,and complexity in railway tunnel engineering CAD software development field in order to finish the whole system by OOP technology.The system also sets up a data access mechanism of user-role-authorization to protect application data safely. Research conclusions:During the development of railway tunnel engineering CAD system,professionals demand-oriented adhere to establishment of designing logic model of framework and sub-systems.The system finished all functions efficiently because it use the OOP technologies to design objects and their reasonable components.The software are having been used to many railway lines and have a good effects.It also will be a reference practice solution because it is easy integration an maintenance.The applications show that technology framework and development methods are practical.
