运用 UDEC 软件模拟影响层状岩土质混合边坡施工稳定性的各种主要因素，在此基础上分析了某高速公路典型岩土质混合路堑边坡的稳定性。结果表明：①土层厚度不同，边坡水平位移不同，且土层对稳定性的影响较岩层敏感得多。②岩层顺倾时，最大水平位移随层面倾角变化先增大后减小；逆倾时，呈现略微减小→增大→减小的趋势。稳定安全系数的变化趋势与边坡最大水平位移恰好相反，这也与工程实际相符。③典型岩土质混合高边坡经加固后处于稳定状态，这与现场监测资料相吻合。

The main factors that impact Soil-Rock Composite slope are simulated by UDEC,while the stability of typical Soil-Rock Composite slope on the Da Liu highway is analyzed through above analy-sis.Calculation results show that:(1 )The horizontal displacement of slope is different from the change of Soil thickness which is more sensitive than the Rock.(2)For consequent slope,the maximum horizontal displacement of slope fist increases then decreases with structural plane dip angle;For anti-dip slope,the outline of curve for the relationship between them shows the trend of slightly decrease-increase-decrease. The trend of the safety factor is contrary with the horizontal displacement,which is in accordance with practical case.(3)The typical Soil-Rock Composite slope is in a stable state after reinforcement,and the practical monitoring data is proof of that.
