生成线路初始平面的自动优化方法
An Automatic Optimization Method for Designing the Initial Horizontal Alignment of New Railway Lines
-
摘要: 为迅速获得合理的线路平面初始方案,将产生线路初始平面的过程分为两个连续的子过程:首先根据 航空折线寻求一条链式折线线路,然后对链式折线线路平面进行圆顺处理,生成直线-曲线-直线型线路平面;再 进行线路平面初步优化设计后,即可得出线路初始平面方案。该方法已用于铁路新线设计智能CAD系统的研 究中。Abstract: In order to obtain a reasonable initial horizontal alignment scheme for optimization of a new railway line quickly, the procedure of the initial horizontal alignment is divided into two stages: 1) to find a chain-linked fold line fromthe centerline ofthe route selected by aerial surveying alignment, based onwhich a straight-curve-straight initial horizontal alignment is then obtained, 2) to generate the initial horizontal alignment scheme of the new railway line by optimization design. The method proposed in this paper has been successfully applied to“the intelligent CAD system for railway location”.
