摘　　要：通过计算,将卵型曲线的不完整缓和曲线段补全,并改变交点的设计参数,使其成为普通曲线,用普通曲线的计算解决卵型曲线的计算难题。结合工程实例,详细介绍了变卵型曲线为普通曲线的计算方法步骤。Through a series of calculations, the incomplete transition curve sec- tion of oval curve was completed, the design parameters of intersection point were changed, and the oval curve became common curve, in this way, the calculation of common curve was used to solve the difficulties of oval calculation. In combination with the project example, the calculation method of oval curve converted to common curve was introduced in detail.
