铁路站场咽喉区优化设计及平面图自动铺画方法研究

铁路车站咽喉区平面设计在站场计算机辅助设计中占有重要的地位,本文运用图论思想对车站咽喉区结构图型进行数学抽象,提出识别咽喉区结构图型中道岔邻接关系的象限推理方法,建立以缩短咽喉长度为优化目标的数学模型,并依此实现利用计算机推算咽喉区最优岔心位置坐标的算法,最后通过实例对文中提出的模型算法进行验证.

Optimal design and research on automatic drawing in railway yard throat zone

The plane design of railway station throat was very important to computer aided design of railway station.This paper described the station throat structure with graph theory,and based on the quadrant reasoning mechanism,proposed a method recognizing the relations of neighboring switch,then presented the optimization model that shortest the length of the throat,and introduced the computer-based algorithms for model that worked out the coordinates of optimal switch centers.At last,the model and algorithms were justified with practical example.
