黄土路堑高边坡横断面形式研究

摘 要：由于黄土的特殊性，结合20 m以上高路堑边坡断面形式的系统研究较少，设计方案缺乏理论性指导。结合实际工程，采用数值分析软件，建立不同工况模型，对比分析综合边坡坡率、开挖断面面积与安全系数之间的关系，结合潜在破裂面迁移规律阐释结构形式安全系数变化机理，为类似工程提供参考。

Abstract： Due to the particularity of loess， there are few systematic studies on the section form of high cut slope above 20 m， and the design scheme lacks theoretical guidance. Combined with the actual project， numerical analysis software was used to establish models under different working conditions， and the relationship between comprehensive slope ratio， excavation section area and safety factor was compared and analyzed. Based on the migration law of potential fracture surface， the variation mechanism of safety factor of structural form was explained， which can provide reference for the construction of similar projects.
