滑坡防治工程效果的模糊综合后评价研究 English Version
Post-fuzzy comprehensive evaluation of effectiveness of landslide control
-
摘要: 通过现场调研比较,筛选出滑坡防治效果的11项后评价因子,包括滑坡本体因子和防治工程因子两大类。进而分析了国内外各种综合评价方法,由于人们对滑坡及治理工程的认识存在不确定性和模糊性,故尝试采用模糊数学方法进行定量或半定量描述,根据滑坡及防治工程特征对后评价效果的影响程度确定其隶属度,并提出修正的功能重要度系数权重确定法来确定权重,初次建立了模糊综合评价模型。Abstract: Based on the analysis of a great deal of field investigation data,11 factors,which include the landslide itself and controlling measurements,were selected.Then,comparing with the current evaluation methods,fuzzy mathematics is adopted since there were difference and fuzzy about the landslide and the effectiveness of its controlling.Furthermore,according to the affecting degree of the factors,subordinate degree of the 11 factors were described quantitatively or half-quantitatively,and the revising weight determination method of forced decision was proposed.Finally,the post-fuzzy comprehensive evaluation model of effectiveness of landslide control was set up.The model,which had been certified preliminarily,was useful and effective.
