摘要
将模糊互补一致性判断矩阵引入AHP法并扩展到模糊环境中,建立了改进的AHP法。并基于此方法确立了基于半定量-半定性指标的滑坡稳定性评价模型,以柳林县贺西黄土老滑坡为例,利用该评价模型对3种工况下的滑坡稳定性进行分析,并将计算结果与传统极限平衡法相比,结果表明,这2种方法具有较好的一致性,而且评价模型的结果与实际情况较为符合,说明该评价模型的合理性与可靠性较高。
The fuzzy complementary consistency judgment matrix is introduced into the AHP method and extended to the fuzzy environment.The improved AHP method is established.Based on this method,the landslide stability evaluation model based on semi-quantitative and semi-qualitative index is established.Taking the old landslide of Hexi loess in Liulin county as an example,the evaluation model is used to analyze the stability of landslide under three project conditions,and the calculated results are compared with the traditional limit equilibrium method.The results show that the two methods have good consistency.Moreover,the results of the evaluation model are more consistent with the actual situation,indicating that the rationality and reliability of the evaluation model are more higher.
