步骤(1)：建立注浆效果评价等级一级指标，由影响一级指标的相应因素确定为二级指标，量化各二级指标的评价等级，确定注浆效果评价等级层次模型。Step (1): Establish the first-level index of grouting effect evaluation grade, determine the corresponding factors that affect the first-level index as the second-level index, quantify the evaluation grade of each second-level index, and determine the level-level model of grouting effect evaluation.
步骤(2)：根据注浆效果评价等级层次模型，确定一、二级评价指标的权向量，进而得出各影响因素对总目标的影响权值；Step (2): According to the grouting effect evaluation grade hierarchy model, determine the weight vectors of the first and second evaluation indicators, and then obtain the influence weight of each influencing factor on the overall goal;
结合层次模型结构，对评价影响因素建立比较判断矩阵A，采用1-9级比例标度对各因素重要性程度赋值并对矩阵进行计算，一般情况下，将aii的权重定义为：Combining with the hierarchical model structure, establish a comparative judgment matrix A for the evaluation influencing factors, and use a 1-9 level scale to assign the importance of each factor and calculate the matrix. In general, the weight of aii is defined as:
其中，CR＝CI/RI，CI＝(λmax-n)/(n-1)；λmax为一致性矩阵的最大特征根；n为成对比较的因子。Among them, CR=CI/RI, CI=(λmax-n)/(n-1); λmax is the largest characteristic root of the consistency matrix; n is a factor for pairwise comparison.
