| 摘 要： | 由于滑坡自身的复杂性和模型方法的适用性等原因，滑坡发生时间的预测预报仍是滑坡学领域的难题之一。本文基于可拓层次分析法原理，建立了滑坡发育阶段判定的物元模型和可拓层次分析法模型。该方法不但具备层次分析法的系统性、层次性和简洁性优点，而且具备可拓学的考虑人类思维模糊性等优点，同时避免了层次分析法中为满足对比矩阵一致性而进行的大量试算，采用基于可能度区间判断矩阵排序法更加符合实际。通过秦安县魏店乡刘萍组北山滑坡实例计算验证，可拓层次分析法能够较好地反映滑坡发育的演变阶段，可进行滑坡中短期时间预报。

| Abstract: | As the complication of the landsides themselves,usefulness of the models,and other reasons,time prediction for landslide is still a problem on landside academic.Based on the Extension AHP principle,this paper establishes the matter-element model and the Extension AHP model to judge development stage of landslides.This method not only has the advantage of AHP(systemic,level,simplicity),but also has the advantage of the Extension which considers the ambiguity of thinking,aroiding a lot of trial work in AHP.Taking example for the north hill's landside in Weidian of Qin'An County,the Extension AHP can reflect well the evolution of landslide development,and can be used for a middle-short prediction of landslide. |
