山坡上墩台基础稳定性的模糊综合评判

Fuzzy Comprehensive Judgment for the Stability of Piers and Abutments that Built on a Hill

建立山坡上墩台基础评判模型,确定了各层次论域子集中的影响因素。利用模糊数学原理,将层次分析法和专家调查法相结合,对山坡墩台基础稳定性进行评判。这种评判方法较好的适应了山坡墩台整体失稳和局部失稳影响因素的复杂性和模糊性,实例分析对此进行了很好的验证。

A model of stability of piers and abutments that built on a hill was set up.Influence factors of the stability of piers and abutments were analyzed.Fuzzy mathematics theory was used,the method of analytical hierarchy process is combined with expert investigation,judgment for the stability of piers and abutments that built on a hill.Furthermore,the method of fuzzy comprehensive is fit to the judgment for the integral stability and local stability of piers and abutments,the effects are complex and fuzziness.A example shows that this method is well fit to it
