摘　　要：影响高速公路软土地基路基沉降因素很多,各因素对软基沉降的敏感性是不同的.软基影响因素分析对于软基处理设计、施工监控有较大的指导意义.提出采用灰色系统理论中的灰色关联分析方法,对高速公路软土地基沉降进行敏感性分析,通过建立软基沉降的灰色关联数据矩阵,进而计算出敏感因子变化与软土地基沉降之间的灰关联系数和灰关联度,从而确定软基沉降的敏感因素.Expressway soft ground settlement is influenced by many factors.The sensitivity of each factor on soft ground is different.Analyzing these factors is of great significance for the design of soft ground treatment and construction monitoring.This paper puts forward grey relational analysis method,which is part of grey system theory,to analyze the sensitivities of different factors on expressway soft ground settlement.By establishing the grey relational data matrix of soft ground settlement,and then calculating the grey relational coefficient and grey relational degree of the change between factors and soft ground settlement,finally,the most sensitive factor of soft ground settlement can be determined.
