高速公路线形与地形协调性评价

摘要

Based on the intersection characteristics of road alignment and terrain contour line,taking the intersection angle and adjacent intersection distance as parameters,the model of coordination evaluation of highway alignment and topography is established.A new highway is evaluated.The result shows that the evaluation curve can help improve design scheme.%基于公路线形与地表等高线的交叉特性,以各交点的交叉角度及相邻交点距离为参数,建立了线形与地形协调性评价模型。选取某新建高速公路试评价,结果表明评价曲线能够辅助改进设计方案。
