基于直线约束的道路线形设计通用方法

Universal method for highway's horizontal alignment based on restrictions of straight line

通过对道路平面线形设计导线法的进一步研究 ,提出了可处理任意线元组合的通用计算方法 ,建立了相应的计算模型 ,发展了导线法 ,使导线法与曲线型设计方法进一步结合 ,并应用于道路CAD中的动态平面交互设计 ,增加了交互手段 ,提高了满足实际设计需要的交互灵活性。

Through the deeper research to traverse method for highway horizontal alignment design,a method for calculating curve combination including all kinds of curve element is presented,and its calculating model is given.This method develops traverse method, and unites the traverse method to the curve design method better. With the application in dynamic and interactive CAD for highway's horizontal alignment, it adds more ways to interactive design for getting more flexibility.
