摘  要：
为研究暴雨诱发作用下高填深挖路基边坡稳定性问题,分析了暴雨诱发碎石边坡失稳机理,研究了暴雨和正常两种计算工况下边坡稳定性,采用摩根斯坦-普赖斯分析方法,分析了两种工况下高填深挖碎石边坡抗剪强度、抗剪能力和边坡安全系数的变化,与正常工况相比,暴雨作用下边坡土体的凝聚力和摩擦强度都显著降低,安全系数显著降低,因此,暴雨导致边坡抗剪强度和抗剪能力明显降低,使安全系数降低,导致边坡失稳现象发生。为高填深挖路基边坡稳定性评价及防治措施提供依据。

摘  要：
To study the stability problem of high filling digging deeply embankment slope resulted from heavy rain,the instablility mechanism of debris slope caused by heavy rain is analyzed.Under two calculation operating conditions,as is heavy rain and normal operating condition,the stability of slope is calculated.The Morgenstern-Price Method is adopted,and the change of the strength,ability of shear strength and safety factor of slope are analyzed.Compared with the calculated rusults under nomal operating condition,under the heavy rain operating condition,the strength and ability of shear strength is much lowed,and the safety factor is much reduced.So heavy rain lows obviously the strength and ability of shear strength and reduces the safety factor,so to result in the slope being collapsed.So it provides evidience for analysis deformations stability assessment and control of high filling digging deeply embankment.
