摘　　要：为了计算主要影响水泥土桩力学性能的侵蚀离子的权重系数,找出腐蚀弱化水泥土桩强度的各侵蚀离子因素之间的相互量化关系,引入模糊层次分析法(AHP)理论,通过建立递阶层次分析体系,构造比较判断矩阵,利用和法计算各级因素的最大特征值max?,一致性检验及计算权重,最后得出可靠、准确的权重系数,这为实际在污染与侵蚀土体上设计与施工水泥土桩复合地基提供了参考依据。To calculate the weight of erosive ion influencing ＆#39; mechanical property of cement-soil piles and find the quantification of these factors which corrode and weaken the strength of cement-soil piles, the theory of analytic hierarchy process（AHP） is introduced. System of hierarchical analysis is constructed and judgment matrix is made. Maximum eigenvalue of each factor is calculated with sum method. Finally consistency test is carried out and weight is calculated to receive reliable, accurate weight, providing theoretical reference for designing and con-structing cement-soil pile composite foundation based on pollutant and erosive earth mass.
