摘要
在道路勘测设计教学过程中,平面交叉口的竖向设计以及相交道路的超高变化和过渡一直困扰大学生。为了更好地使得学生对上述问题有深刻和直观的理解,利用三维激光扫描技术对实际平面交叉口进行扫描,然后重建交叉口的模型,这样学生们对于交叉口范围的高程以及相交道路超高的变化和过渡等都有了清晰的认识,取得了理想的效果。
In the course of road survey and design teaching,the vertical design of intersections and the super elevation changes and transitions of intersecting roads have plagued university students.In order to enable students to have a deep and intuitive understanding of the above issues,use 3 D laser scanning technology to scan the actual intersection and rebuild the model of the intersection.In this way,the students have a clear understanding of the elevation of the intersection range,as well as the changes and transitions of the intersecting roads,which achieved ideal results.
