摘要
太行山是我国二三级阶梯分界线之一,分界线上地形变化急剧,区域地形陡峭,自然横坡大,地势落差大,局部垂直落差达二三百米,即太行山断崖式地形。针对这类地形的特点,以G341平顺县境内王庄至晋豫省界段工程为例,对该地形条件下的公路路线方案进行研究,探索类似地形条件下的公路选线方法。
Taihang mountain is one of the second and third echelon dividing lines in China.The terrain on the dividing line changes rapidly.The regional terrain is steep,the natural cross slope is large,the terrain drop is large,and the local vertical drop is up to 200~300 meters,which is the cliff type terrain of Taihang mountain.According to the characteristics of this kind of terrain,this paper takes the project from Wangzhuang to the boundary of Shanxi and Henan province in G341 Pingshun county as an example,studies the highway route scheme under this terrain,and explores the highway route selection method under similar terrain conditions.
