摘　　要：以赣州瑞金市叶坪乡黄沙村华屋村红层滑坡为例,采用数值分析软件FLAC对滑坡外部滑动特征及内部力学变化特征进行了研究,探讨了红土层滑坡的破坏机理,认为:开挖是引起滑坡破坏的主要因素,由于坡体内部应力分布相当复杂,任何形式的扰动均会引起坡体失稳。提出了针对江西红土层滑坡的处理方法及注意事项,为处理江西等地特有的红层滑坡提供了相关依据,也为今后避免该类事故的发生提供了预防措施。Taking the red layer landslide in Yeping,Ruijin City of Jiangxi Province as an example,the external characteristics and internal mechanic variation of the landslide are analyzed by numerical analysis software of FLAC and the failure mechanism is explored.The analysis results demonstrate that the excavation is the main factor causing the landslide failure,due to complicated internal stress distribution of the landslide,any form of disturbances will cause the landslide instability.The treatment method and the remarks aiming at the red layer landslide in Jiangxi Province are put forward,which provides correlative basis for solving the treatment of red layer landslide specially existed in Jiangxi Province and the prevention measures for similar accidents in future.
