摘　　要：针对单体滑坡危险状态分析不全面的问题,提出了一种基于滑坡累积位移的滑坡体危险状态多角度分析方法。首先,利用极限位移准则确定滑坡所处预警阶段;其次,利用尖点突变理论对滑坡稳定状态进行评价;再次,采用重标极差分析确定滑坡体的发展趋势;然后,建立模糊矩阵确定滑坡体危险状态,但由于单个检测点无法准确反映滑坡整体危险状态,故采用多个监测点综合判断滑坡整体危险状态;最后,将该方法应用于八字门滑坡,验证其有效性。结果表明该方法能够有效地判断滑坡局部及整体的危险状态。To solve the problem of incomplete analysis of individual landslide hazardous states,this paper proposes a multiple perspective analysis method of landslide's hazardous state based on landslide cumulative displacement.Firstly,the limit displacement criterion is used to determine the early warning stage where the landslide locates.Secondly,the landslide stable state is evaluated by the cusp mutation theory.Thirdly,the development trend of the landslide mass is determined by using rescaled range analysis.Then,the fuzzy matrix is established to determine the hazardous state of the landslide.However,since a single detection point cannot accurately reflect the overall hazardous state of the landslide,multiple monitoring points are used to identify the overall hazardous state of the landslide.Finally,the method is applied to the Bazimen landslide to verify its effectiveness.The results show that this method can effectively identify the local and the whole hazardous state of the landslide.
