摘要
以某边坡为实例,分别进行了灰色关联法与层次分析法修正的灰色关联法的敏感度计算,对比可以发现,层次分析法修正的灰色关联模型中,土体的内摩擦角与粘聚力对安全系数的影响排序结果与未修正结果相同,但坡高、容重与坡率的排序发生了变化,经分析,认为修正的结果更具有参考性。
A slope for example, the sensitivity was computed by Grey-correlation degree analysis method and AHP modified Grey-correlation degree method, respectively. AHP Grey-correlation degree relational model correction method, the soil friction angle and cohesion influence on the safety factor of the results were the same sort of correction results, but the slope high that changed, the bulk density and slope rate of sorting by analysis that correction results of more reference.
