摘要
以西南地区某滑坡为例,采用ABAQUS有限元软件,研究降雨入渗对含软弱夹层滑坡的稳定性影响。结合实际施工工序,模拟原始滑坡、有支护结构无降雨作用、有支护结构有降雨作用的滑坡变形特征,对比在不同雨水入渗强度下滑坡的稳定系数,综合评价降雨入渗的瞬态渗流作用对含软弱夹层滑坡稳定性的影响规律,并提出排水措施优化设计。
Taking the landslide in southwestern China as an example,the impact of rainfall on the landslide with weak interlayer is studied by ABAQUS software.Combined with the actual construction process,it stimulated the deformational characteristics of the different landslide model,including the primary landslide,the landslide with supporting structures but without rainfall,as well as the landslide with supporting structures and rainfall.By comparing the stability coefficient of landslide under different rainfall infiltration intensity,the influence law of transient seepage effect of rainfall infiltration on the stability of landslide with weak interlayer is comprehensively evaluated,and the optimal design of drainage measures is proposed.
