摘要
以一倾斜分层的渣土堆积层边坡模型为例,研究了不同雨量峰值分布的倾斜下对渣土堆积层边坡稳定性的影响。分析表明,受降雨影响渣土堆积层边坡前部坡体孔隙水压逐渐抬升,不同降雨条件促使地下水逐渐向前缘坡体渗流;降雨期的峰值集中在降雨的时期危险性从大到小排列总体规律是中后期>前期,其中不同雨型之间又有所差别。
This paper takes the slope model of a slope with inclined stratification as an example to study the influence of different peak rainfall distributions on the stability of the slope.The analysis shows that the pore water pressure of the front slope of the residual soil accumulation layer under the influence of rainfall increases gradually,and different rainfall conditions promote the seepage of groundwater in the front slope gradually.The peak value of rainfall period is concentrated in the period of rainfall,and the risk is arranged from large to small.The general rule is that the risk in the middle and late stage is greater than that in the early stage,and there are differences between different rainfall types.
