摘要
本文通过调查统计方法,对内蒙古境内3条草原公路线形指标进行调查统计,并比较了现有公路线形设计规范中各指标的规范值,得出草原公路线形指标参数选取普遍较高。进一步总结出内蒙古境内草原公路总体平面直线多,平曲线少,平曲线半径大。纵断面变坡点多,坡度平缓,竖曲线数量频繁,半径指标高,平、纵线形指标不均匀的特征,为后续草原公路线形相关研究奠定基础。
This paper have surveyed three grassland roads in Inner Mongolia steppe by statistical method,and obtained characteristics which the Linear index of grassland roads alignment is generally higher compared with the normative values of each index of the existing highway alignment design specification.Further,this paper summarized characteristics of grassland roads alignment that the number of liner is plenty and the number of horizontal curve is scarce and the radius of horizontal curve is large;The change of slope is abundant and flat;the change of vertical curve is Frequent;the index of horizontal curve and vertical curve is uniform.these statistical results lay the foundation for follow-up prairie research.
