摘　　要：为进一步明确堆积体边坡的滑动破坏机理与稳定性分析,本文以实际工程为研究对象,对雨季期间堆积体边坡的监测数据进行分析,分析结果表明该堆积体边坡变形主要受降雨条件影响,降雨过程主要通过引起地下水文地质条件变化,进而引起堆积体边坡变形破坏,且变形具有一定滞后性。本文还对降雨条件下的堆积体边坡变形规律进行了划分,并给出各阶段的变形机理。此外,通过采用不平衡推力法对该边坡进行分析发现,在暴雨状态下,边坡稳定性系数最小仅为1.021,处于欠稳定状态。本文研究内容能够为堆积体边坡变形与稳定性分析提供规律支持。In order to further clarify the sliding failure mechanism and stability analysis of the deposit landslide,this paper takes the actual project as the research object,and analyzes the monitoring data of the deposit slope during the rainy season.The analysis results show that the deformation of the deposit slope is mainly affected by the rainfall conditions.The rainfall process mainly causes the deformation and failure of the deposit slope by causing changes in underground hydrogeological conditions,and the deformation has a certain lag.This paper also divides the deformation law of the accumulation slope under rainfall conditions,and gives the deformation mechanism of each stage.In addition,by using the unbalanced thrust method to analyze the slope,it is found that the minimum stability coefficient of the slope is only 1.021 under the rainstorm condition,which is in an unstable state.The research content of this paper can provide regular support for the deformation and stability analysis of accumulation slope.
