山区公路陡坡路段选线研究

Research on Route Selection for Abrupt Slope Section of Mountain Highway

山区公路选线时受地形条件限制,路基边坡往往出现高填深挖的情况,施工时高填深挖经常会影响路基的安全性及稳定性,在前期选线时为有效减少路基边坡的高填深挖,推荐采用由纵断反推出平面的方法,并对此进行分析研究,供相关人员参考。

Limited by topographic condition, the subgrade side slope is often with high filling and deep excavation in the route selection for mountain highway. During the construction, high filling and deep excavation often influence the safety and stability of subgrade. In order to effectively reduce high filling and deep excavation of subgrade side slope in the early route selection, the method of adopting longitudinal section to obtain the plane is recommended, and the analytical research is made, so as to provide reference for relevant personnel.
