摘要：

针对滑坡治理以后的稳定状态综合评价问题，从影响因素多因子多层次角度出发，构建综合评价决策模型，提出了滑坡治理稳定状态综合评价的耦合权重确定方法，即基于优先关系排序-二元相对比较的权重计算确定方法，以避免一致性检验，减少评判的主观性，还采用程序编程语言编制了相应计算分析程序。在此基础上，结合杭金衢K103滑坡的地形地质条件和工程治理情况，采用基于耦合权重的滑坡治理稳定状态综合评判方法，进行其历经治理的稳定状态分析和效果评价。研究结果表明：滑坡历经综合治理，所处的稳定状态等级区间为基本稳定状态（E_II）；各项工程措施充分发挥功能效应，稳定系数由0.98提高至1.20，滑坡整体稳定，安全储备充足。

Abstract:

In order to resolve the problem of steady-state comprehensive evaluation of landslide through engineering treatment, the model of comprehensive evaluation is constructed and used to implement steady-state decision analysis and treatment effect evaluation of landslide after comprehensive treatment. The determination method of coupling weight value which is based on precedence relation sequence and binary relative comparison is proposed. Simultaneously, the method which needn’t consistency test can reduce subjectivity and improve scientific rationality. Moreover, in order to improve processing capability and computing speed of model, the calculation and analysis procedure is developed. Based on topography and geological condition and engineering treatment situation of K103 landslide along the highway of Hangzhou-Jinhua-Lishui, the method of comprehensive evaluation with coupling weight value for steadystate of landslide after treatment is applied in implementing steadystate analysis and treatment effect evaluation of landslide. The research results show that the landslide through comprehensive treatment is in stable state(E_Ⅱ). The various engineering measures exert functional effects fully, and safety factor of the landslide is improved from 0.98 to 1.20. After comprehensive treatment, the landslide is stable and safe.
