分析地铁线路平纵断面设计与地铁调线调坡设计间的关系,将地铁线路设计CAD技术应用到地铁调线调坡设计中,提出"双边线形约束"优化算法理论,系统介绍双边线形约束的基本特性和目标函数及约束条件;并提出地铁调线调坡设计中基于距离法和面积法的优化算法。将该理论和算法应用于地铁调线调坡优化设计软件中,并给出地铁调线调坡优化设计系统的构成模块:数据编辑模块、平面设计模块、纵断面设计模块和图表输出模块等。结合设计实例,说明地铁调线调坡优化设计的具体操纵过程。
Analyses the relationship between the design of the Metro line and that of the line and slope fine-tuning,applies effectively the CAD technology in the design of the Metro line into the design of the line and slope fine-tuning,puts forward a theory of the optimization algorithm ＂bilateral linetype constraint＂,introduces the essential characters,object function and constraint conditions.Then this paper presents the optimization theory and algorithm based on the distance-method and area-method for the design of the line and slope fine-tuning.In the end,the author puts the theory and algorithm into practice while developing the system of metro line and slope fine-tuning which includes several modules to be programmed,such as data editing,plane designing vertical section designing and charts output modules.This theory has been applied into the software and we achieve a good result.
