高等级道路平面线形设计方法

阐述了直线、圆曲线、缓和曲线三要素的基本理论及设计方法,着重探讨了圆曲线与缓和曲线的应用条件,分析了圆曲线与缓和曲线的长度关系,并提出了高等级道路平面线形设计中应遵循的原则及要求。

Linear plane design method of high-class highway

It illustrates the basic theories and design method of straight line,round curve,moderate curve,puts a stress on the discussion of the applying conditions of round curve and moderate curve,analyses the length relation between round curve and moderate curve,and puts forward the principles and requirements should be followed in the linear plane design of high-class highway.
