【摘要】 论文论述了一般路基横断面及排水用地图CAD系统中的设计方法及相关技术。 一般路基横断面在横断面设计中设计工作量很大,需要计算机辅助设计可以节省大量人力,提高设计效率。系统直接利用既有设计成果作为横断面设计的基础数据,通过对各种路基横断面的抽象,提出参数化及可组合的标准横断面模型,适用于各种路基横断面的设计。系统直接采用AutoCAD数据库,根据基础数据在AutoCAD中构建横断面,并利用其标准属性框实现横断面属性的修改,系统提供便捷的交互式设计工具用于横断面的修改和附加线的设计,并在横断面面积的计算及适时更新上提出新的实现方法。横断面设计完成后的DWG文件还可以作为其它设计的数据源。 路基排水用地设计与横断面设计成果直接相关。在排水用地设计中,为电子平面图形能完整保持线路信息,提出图纸空间折图及线路区域划分思想。系统直接利用横断面设计成果,实现在电子平面图纸上设计排水设施和线路用地界。 论文在详细介绍相关开发过程后,还重点介绍了程序开发技术,包括面对对象技术、COM技术、自定义实体技术、OPM技术及反应器技术等。 论文在最后用具体的实例验证系统横断面及排水用地自动和交互式设计,体现出系统的便捷性和准确性。 系统是在Windows NT 5.0操作系统上进行开发的,采用了目前最为优秀的Windows平台开发工具之一——Visual C++ 6.0作为系统开发平台;选用了集绘图和开发为一体的计算机辅助设计系统——AutoCAD 2000作为图形支撑环境;同时应用了AutoCAD最强有力的二次开发工具ObjectARX 2000进行系统开发。更多还原

【Abstract】 This thesis discussed the design method and related technology of general cross section and railway-use land & subgrade drainage.Railway general road bed cross section design work load to be very much heavy , use the aided designing technique of the computer, can save a large number of manpower, improve design efficiency. This system used designed data such as rail plane and vertical section information as base data, come to a normal cross section model which can meet all kinds of standards, construct cross section entities in CAD system directly which can be modifid by CAD normal property window, system also offer design tools for cross section modify and auxiliary lines design, what’s more, a new method applied to area calculation and update accordingly is offered.The process of subgrade drainage and railway-use land design is related with cross section design directly. In this process, in order to keep railway information integrated in electricity drawing, fold plane electricity drawing in paper space and compartmentalize railway regions was realized in this system. So system can implement design drainage and railway-use land in electricity drawing directly by cross section products.At the end of the thesis, there is a vivid example provided, which proved veracity, stable in operation and easy in conduction of this system.This system is developed under the operation system named Wind ows NT 5.0. Its developing flat roof is Visual C++ 6.0, now one of the most perfect developing flat roofs based on Windows. Its gragh-supported environment is AutoCAD 2002, a CAD system composed of pioting and developing. The programming language is ObjectARX 2000, the most powerful one used for secondary development in the development tools of AutoCAD 2000.更多还原
