双线性Coons曲面在平面交叉口竖向设计中的应用

Application of bilinear Coons surface to design of intersection

从构造合理数字模型的角度,讨论了在进行城市道路平面交叉口CAD技术中,怎样结合传统的平面交叉口竖向设计构造计算等高线的等分法来构造双线性Coons曲面,从而来模拟城市道路平面交叉口的设计面,并且实现了设计模型中点的定义计算和设计等高线的形成。

Discusses from the view point of designing rational digital models how to do engineering design of intersection by integrating calculated lines into Bilinear Coons Surface,thereby simulating the intersection design surface,and defining the point in the surface corresponding to the contour line.
