摘　　要：雷西高速公路位于黄土高原区陇东黄土高原亚区,该亚区是我国黄土高原地貌特征表现最为典型的区域.文中运用数值分析的方法,选取典型的生态防护边坡,利用FLAC3D软件分别建立含植物根系和无植物根系的边坡模型,对不同坡比的边坡进行稳定性的对比分析,从理论上验证了生态防护对边坡稳定性的作用.Lei Xi high‐speed is located in Longdong Loess Plateau sub region of the Loess Plateau Area , which is the most typical part for the features of landform in Loess Plateau in China .This paper mainly uses the method of numerical analysis ,with the typical slope in highway chosen ,and the corresponding models were established with plant root and non root by using the software FLAC 3D .Then through the comparison and analysis of the stability of the slope ,and in consideration of the influence of differ‐ent slope ratio ,the effect of ecological protection was verified theoretically .
