复杂交叉口竖向设计方法──区域等高线法

Local Contour Metho──Vertical Design for Complicated Intersections

本文在分析了交叉口坚向设计的各种方法以及计算网格划分的各种方法基础之上提出一种适合于计算机辅助设计方法—区域等高线法。该法适用于各种路面结构和各种形式的交叉口设计，可使设计效率、计算精度和制图质量大大提高，具有广泛的实用价值。

Based on different methods of vertical design for intersections and division of thecalculation network, the local contour method is proposed which is suitable for CAD, and applicable to the design for different pavement structures and intersections. The method is of highvalue in wide application, raising greaily the design efficiency, calculation accuracy and drawingquality.
