摘　　要：在多幅路设计中,由于内外侧路面的超高旋转轴不同、路面横坡的变化范围不一致,使得内外侧路面的超高过渡计算有差异.文章主要探讨了多幅路的缓和曲线长度与超高过渡段之间的关系,并通过工程实例指出,为保证线形协调和超高渐变率满足要求,超高过渡段与缓和曲线长可取不同数值,内外侧路面的超高过渡段也可采用不同数值.In multiple-road design,the superelevation rotating shaft is different between the inner and outer surface,along withinconsistent range road cross slope,so that the calculation of the inner and outer surface of the superelevation-transition calculate isdifferent.We mainly explored the relationship between the length of transition-curve and the superelevation-transition ofmultiple-road,then through the engineering examples,indicated that in order to make sure the coordination andsuperelevation-gradient-ratio could meet the requirements,the superelevation-transition-section and transition-curve long may takedifferent values,superelevation-transition-section inside and outside of the road may also be different values.
