摘　　要：2008年5月8日,受地震影响,四川省茂县南新镇羊毛坪发生严重滑坡。通过对滑坡的形态特征、物质组成、结构特征及岩土体物理力学参数,分析了滑坡变形特征,得到了滑坡影响因素与变形破坏机制,利用传递系数法分别对滑坡在不同工况下的稳定性进行了计算和评价。In May 8,2008,a landslide took place in Nanxin town,Mao County,Sichuan Province because of the effect of earthquake.By studying the character of morphology and structure,the composition of material and the parameters of physical and mechanical,we analyzed the deformation characteristics of the landslide and we got the influence factors and the mechanism of deformation.We used transfer coefficient methods for the calculation and evaluation of landslide stability under different conditions.

关 键 词：滑坡 影响因素 变形破坏机制 稳定性评价
