研究目的:拢口部分的设计是既有线改建设计工作的重要内容,然而目前国内外针对拢口计算机辅助设计方面的研究尚不多见,为提高拢口部分设计的质量,本文研究了拢口计算机辅助设计的方法,并采用VisualC++.net2002开发平台以及ObjectARX二次开发技术,研发了拢口计算机辅助设计模块。研究结论:该模块成功应用于成都至重庆铁路扩能改造设计中,结果表明:该模块界面友好,性能稳定;可以根据设定的线间距自动地搜索出拢口的范围并计算出拢口范围内平、纵信息;可以对拢口范围内平面参数根据设计规范进行违规检测,对错误信息给出警示,并可通过跟踪显示,跟踪到错误地段;可以快速准确地绘制拢口范围内平面图和详细横断面图,为设计者检查拢口设计的合理性提供了一个直观的平台,提高设计质量。
Research purposes: The design of the part of the mouth is an important part of the design of the existing line rebuilding. However, at home and abroad, the researches on computer aided design of the mouth are still rare. In order to improve the quality of the part of the design, Computer-aided design methods, and using VisualC + +. Net2002 development platform and ObjectARX secondary development technology, research and development of a computer-aided design module mouth. Research conclusions: The module has been successfully applied in the design of Chengdu-Chongqing railway expansion reconstruction. The results show that the module has friendly interface and stable performance. The range of the outlet can be automatically searched according to the set line spacing and the range Within the flat, longitudinal information; can be bound to the range of plane parameters in accordance with the design specifications of non-compliance testing, warning of the error message, and through the tracking display, tracking to the wrong location; you can quickly and accurately draw a plan within the bounds of the mouth and The detailed cross-sectional view provides an intuitive platform for the designer to check the rationality of the design of the bib and to improve the design quality.
