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。
The graphic design of the throat area of the railway station occupies an important position in the computer aided design of the station yard. This paper uses the theory of graph theory to mathematically abstract the structure of the throat area of the station, puts forward the quadrant inference method for identifying the adjacent relations of the turnout in the throat area structural drawing, The mathematical model of shortening the length of throat is set as the optimization goal. Based on this, the algorithm of calculating the optimal position of the throat area in the throat area by computer is established. Finally, the model algorithm proposed in this paper is validated by an example.
