摘　　要：互通式立交连接部构造复杂,尤其在变速车道,主线外侧边宽随着匝道走向及外侧边宽变化而变化,路幅外缘坐标难以计算。在桥梁上部结构布置等设计场景,存在效率低、易出错、难变更等突出问题。本文通过对互通式立交连接部的特征段落划分,根据路线设计参数进行特征点桩号计算、主从路线方向计算、附加方位和被附加方位计算,实现变速车道任意位置宽度计算,由数据驱动图形,为工程数字化赋能。The structure of the interchange connection is complex,especially in the variable speed lane,the outer side width of the main line changes with the change of the ramp and the outer side width,and the coordinates of the outer edge of the road width are difficult to calculate.In design scenarios such as the layout of the bridge superstructure,there are outstanding problems such as low efficiency,easy to make mistakes,and difficult to change.In this paper,through the division of the characteristic sections of the interchange connection,the characteristic point station calculation,the master-slave route direction calculation,the additional azimuth and the attached azimuth calculation are carried out according to the route design parameters,and finally the width of the variable lane at any position is calculated,and the data-driven graphics empower the engineering digitalization.
