摘　　要：为使平曲线加宽后公路曲线舒顺流畅,接近于汽车轮胎的运动轨迹,路容更为美观,对用回旋线作为加宽缓和段内侧边线的问题,运用微积分和相关的计算机软件进行了研究,总结出了在平曲线加宽缓和段内侧设置回旋线的设计方法和步骤,并用实例进行了验证。In order to make highway curve smooth and close to the motion track of automobile tires, as well as make the road appearance more beautiful after horizontal curve widening, the differentiation and integration are used to study the problem of using clothoid as the inner sideline of widening transition zone through relative software, and the design method and programme of setting in the inner side of horizontal curve widening transition are found out. They are tested by practical examples.
