多耦合约束条件下铁路站场总体布置图自动生成方法研究
|
摘要
针对铁路站场总体布置图绘制时多耦合约束的难点,基于分阶段处理耦合约束的思想,提出"断面扫描法"处理设备坐标的相对位置约束,而后将"自适应分段多比例法"用于解决比例协调约束,在最后的约束调整过程中,应用"相交可行域法",实现道岔及股道相关约束的自动处理。该研究可快速建立站场设备从原方案到总体布置图的坐标映射,实现满足所有约束条件的总体布置图的自动生成。研究成果已在若尔盖、开原西等多个站场设计中成功应用。
Aiming at the difficulties of multi-coupling constraints when drawing the overall layout of railway station and based on the idea of staging the coupling constraint in the railway station, this paper firstly proposed the method of "cross-sectional scanning" to deal with the relative position constraints of equipment coordinates, then used "adaptive segmentation and multi-proportion method" to solve the scale coordination constraint, and finally, in the process of constraint adjusting, the "intersecting feasible domain" was applied to realize the automatic processing of the turnout and orbit-related constraints. This method can build the coordinate mapping of the railway station equipment from the original plan to the overall layout quickly, and finally, generate the overall layout that satisfies all the constraints automatically. These research results have been applied in the design of several railway stations, such as Kaiyuanxi station and Ruoergai station successfully.
