摘　　要：碎石土高边坡是路基工程中一种常见的特殊路基,对于需要加固的不稳定路堑高边坡,潜在不稳定面的确定是最重要也是首要的问题,提出采用GEO-slope/w搜索潜在不稳定面并对不稳定面进行修正,利用修正后的不稳定面作为边坡加固的潜在不稳定面,按照不平衡推力法计算边坡的设计下滑力的方法加以解决。High gravel soil slope is commonly special in subgrade engineering. For unstable cutting slope that need to be reinforced, confirmation of surface that is unstable potentially has the priority. Firstly, the surface is searched by GEO-slope/w for the purpose of correction, and then taking the corrected surface as the potential unstable surface requiring reinforcement, it will be solved by calculating the designed sliding power of the slope through imbalance thrust force method.
