摘　　要：根据太原市阳曲县小南坡街崩塌的基本特征和变形趋势,研究水作用下的黄土崩塌变形破坏模式和形成机理。通过数值模拟可知,小南坡街黄土坡体首先在边坡坡脚处发生塑性变形,且坡体顶部裂隙不断发育,二者贯通后引发垮塌。Based on the basic characteristics and deformation trends of the Xiaonanpo Street collapse in Yangqu county,Taiyuan city,this study investigates the deformation and failure modes and formation mechanisms of loess collapse under water action.Through numerical simulation,it can be concluded that the loess slope of Xiaonanpo Street first undergoes plastic deformation at the foot of the slope,and cracks continue to develop at the top of the slope,leading to collapse after the two connect.
