以延安新区13标段北端110 m黄土高填方边坡为研究对象，对填筑体的工程性质进行了大量室内试验研究，根据研究区边坡的地质条件和填方边坡的实际情况，选择合理的计算模型采用极限平衡法分别计算出天然、暴雨及地震工况下不同地下水位的边坡安全系数；利用有限元法模拟分析填方高边坡在不同地下水位下的变形特征及应变分布规律。结果表明：延安新区黄土高填方边坡整体处于稳定状态，地震和地下水位的变化是影响边坡稳定性的主要因素；边坡中部和坡脚处的水平位移较大，最大垂向位移发生在填方厚度较大的坡顶处。

The object studied here is a high-filled loess slope with the height of 110 meters .It is located in the north of the No .13 site of Yan’an new district .Based on the geological condition and practical situation of the loess slope ,a proper caculation model was established to caculate the slope safety coefficients at different undergrond water level under narmal weather ,heavy rainfall and earthquakes .And then the finite element method was adopted to simulate and analyse the deformation characteristics and strain distribution law of high-filled slopes at different level of undergound water .The results suggest that the high-filled loess slope in Yan’an district is stable as a whole ;the changes of underground water level and earthquakes are the main factors that affect the slope stability ;the horizontal displacement becomes larger at the middle and bottom of the slope ;the largest vertical displacement accurs at the top of the slope where the fill is thickest .
