为研究含水率、干密度、冷端温度、荷载对冻胀融沉特性影响的程度,建立灰色关联分析模型,对南京地区浅表层淤泥质粘土冻胀融沉试验数据进行计算,分析了各种因素对冻胀系数、融沉系数影响程度。结果表明：影响冻胀系数、融沉系数依次都为含水率、冷端温度、干密度、荷载,证明采用灰色关联分析影响冻胀、融沉因素的显著程度是准确可行的,是一种很好的分析方法。
為研究含水率、榦密度、冷耑溫度、荷載對凍脹融沉特性影響的程度,建立灰色關聯分析模型,對南京地區淺錶層淤泥質粘土凍脹融沉試驗數據進行計算,分析瞭各種因素對凍脹繫數、融沉繫數影響程度。結果錶明：影響凍脹繫數、融沉繫數依次都為含水率、冷耑溫度、榦密度、荷載,證明採用灰色關聯分析影響凍脹、融沉因素的顯著程度是準確可行的,是一種很好的分析方法。

In order to study the extent of water content,dry density,cold end temperature and load influencing frost heaving and thaw collapsing,the model of grey relational preponderance analysis is established to calculate the test data of frost heaving and thaw collapsing of mucky clay at shallow strata in Nanjing region and to analyze various factors influencing the coefficients of frost heaving and thaw collapsing.The result shows that the factors influencing the two coefficients in turn are water content,cold end temperature,dry density,and load;and demonstrates that the use of grey relational preponderance analysis is accurate and feasible.It is a good method for analysis.
