摘　　要：层次分析法(AHP)在地下空间开发难度评估中被广泛使用,该方法是通过对各影响指标进行打分构造判断矩阵进行权重求解,但是在对指标进行打分的过程中,存在很强的主观性,对评估结果造成不可避免的误差。鉴于此,该文提出一种AHP权重修正的方法,用于消除判断矩阵的主观性,获得更准确的权重向量。并以江苏省某城市地下空间开发难度评估为例,应用该方法修正AHP方法获得的权重向量,与未修正的各个权重向量进行对比。结果表明,该方法能够有效地消除各个判断矩阵的主观因素,能更准确地获得地下空间开发难度的各个影响指标的权重。The Analytic Hierarchy Process(AHP)is widely used in the difficulty assessment of underground space development.This method calculates the weight of each influence index by scoring the judgment matrix,but there is a strong subjectivity in the process of scoring the index,which causes inevitable errors to the evaluation results.In view of this,this paper proposes a method of AHP weight correction,which is used to eliminate the subjectivity of the judgment matrix and obtain more accurate weight vectors.Taking the evaluation of the difficulty of underground space development in a city in Jiangsu Province as an example,this method is used to modify the weight vector obtained by AHP method,and compared with each unmodified weight vector.The results show that this method can effectively eliminate the subjective factors of each judgment matrix and obtain the weight of each index of the difficulty of underground space development more accurately.
