针对K39+715堆积型中型土质滑坡，简要描述了边坡的变形及其对公路路基及桥梁的影响，并从滑坡区的现场地质环境、地形地貌、水文地质特征、区域地质构造及人类活动等相关方面对边坡变形进行了分析，滑坡现处于蠕动挤压变形阶段，强降雨对边坡变形起加速及触发作用。基于传递系数法对边坡在自重；自重+地下水；自重+暴雨+地下水；自重+地震+地下水四种工况的稳定性进行了计算，确定了在不同工况下的安全系数，并提出了滑坡处治建议。结果表明：滑坡目前处于极限稳定状态，随着时间的推移和雨季来临，滑坡会进一步发展扩大和滑移。

Slope deformation and its effect on the highway roadbed and bridge of the K39+715 accumulation type medium soil landslide is briefly described, and a detailed analysis of slope deformation is made from the geological environment, topography, hydrogeological feature, regional geological structure, human activities and other related aspects. Currently landslide is in the peristaltic extrusion stage, and slope deformation is accelerated and touched off by the expansion of highway and heavy rain. Based on the transfer coefficient method, the stability of four working conditions: weight; weight and groundwater; weight, rainstorm and groundwater; weight, earthquake and groundwater are calculated, the safety factor under different working conditions is determined, and some suggestions of landslide treatment are put forward. The results show that the landslide is in the limit equilibrium state, with the passage of time and the coming of the rainy season, it will further expand and slip.
