一种公路平面线形曲线型设计方法的探讨

分析了公路平面线形直线型设计法的不足,提出曲线型设计法研究的必要性。重点研究一种非常有前途和适用于公路路线CAD系统开发的算法———基于端点约束受限法,此方法可以解决任何平面线形的组合形式,便于应用和交互式图形CAD软件的开发。

Discussion of a curve design method of highway alignment

This paper analyzes the deficiency of the straight design method of highway alignment and puts forward the necessity of the researching curve design method.In this part the paper strain researches a calculate method that has good outlook and applies to the developing the highway alignment CAD system-restricted method based on endpoint restricting,this method can solve any kind of highway alignment's combinational forms,and it convenient to the developing and applying of the interaction graphics CAD system.
