公路定线方法的研究

Study on Method of Highway Alignment

通过案例的方式,对直线型定线和曲线型定线两种定线方法的全过程进行了分析、比较,探讨了目前公路定线设计中对于曲线型定线法认识不足的实际情况.研究表明:对于高等级公路设计、立体交叉设计,以及在复杂地形条件下的其他公路设计,曲线型定线法比直线型定线法具有明显的优越性;随着各种计算机辅助路线设计软件的出现,曲线型定线法将会得到广泛的应用.

Through case studiest,his paper analyzes the methods of linear alignment and curvilinear alignment,and discusses the actual situation for study on the method of highway alignment.The results show that the method of curvilinear alignment has an advantage over the method of linear alignment in designing highwayt,hree-dimensional crossroad and other highway under the conditions of complex topography.As different versions of computer-aided route design software are createdt,he method of curvilinear alignment will be widely used.
