摘　　要：为了研究岩质边坡土钉支护后路堑边坡的稳定性效果,在广东梅县梅江河右岸坡麓段路堑右侧采用了土钉墙支护方案.应用PhaseⅡ程序建立了分析模型,并运用非线性有限元法对岩质边坡土钉支护稳定性进行了数值计算.结果表明,土钉支护岩质边坡的稳定性好,而且经济可行,安全可靠.The soil nail reinforced method is often used in the soil slope reinforcement in the road chasm to assure the slope stability. The nonlinear finite element analysis is carried out to analyze the rock slope stability using soil nail reinforcement method numerically. The rock mass stability and displacement field are analyzed for the soil slope based on the soil nail reinforcement. The numerical analysis results show that the rock mass slope is in stable state and is reliable cost effective.
