南京工学院道路教研组李方副教授最近研究成功一种新的路线线形设计方法。这种方法以不完整的缓和曲线连同圆曲线组合成线形设计基本单元,吸取了国外曲线形设计方法的精髓,保留了我国习用方法的设计方式,可以用来毫无限制地设计任何曲线组合形式,例如普通曲线、复曲线、回头曲线,单卵形或任意多卵形以及任何形式的卵形曲线,s形曲线等等。该方法考虑到目前我国尚未生产回旋曲线板和进口价格昂贵的现状,研究了一种藉助PC-1500便携式袖珍计
Associate Professor Li Fang of Nanjing Institute of Road Education and Research recently studied a new route alignment design method. This method combines incomplete curve and circular curve into the basic unit of linear design, absorbs the essence of the overseas curve-shaped design method, retains the design method of our country’s traditional method, and can be used to design any curve combination without limitation Such as normal curves, complex curves, retro curves, single or any number of ovals and any form of oval, s-curve, and the like. This method takes into account the present situation that our country has not produced the clothoid curve plate and the import is expensive, and has studied a kind of portable pocket meter
