摘　　要：斗嘴斜坡在地震和连续暴雨的情况下产生了变形,对斜坡稳定性产生了不利影响。在现场调查、测绘、勘探以及室内试验结果的基础上,阐述了斗嘴斜坡的变形特征,分析了该斜坡的变形机制,并对三种典型工况下斜坡的稳定性进行了定量计算,结果表明该斜坡整体稳定性较好,但#2边坡坡脚面临公路,人类活动频繁,建议采用修建护脚墙和地表截排水沟的防治措施,防治边坡失稳。Douzhui slope was deformed under earthquake and continuous rainstorm, which had a negative impact on slope stability. On the basis of site survey, mapping, exploration and indoor test, the deformation characteristics of Douzhui slope are described and the deformation mechanism is analyzed in this paper. The stability of the slope under three typical conditions is separately calculated qualitatively. The results showed that this slope is basically stable, but the toe of #2 slope is facing the road, where human activities are frequent. Therefore, it is recommended to build toe wall and surface drainage ditch to prevent slope instability.
