摘要
按均匀正交设计方法人工配制含盐量、含水率、干密度三因素三水平的粘性土样,通过剪切试验测定饱和与非饱和状态下土的抗剪强度。运用投影寻踪回归分析法(PPR)研究各因素对粘性土抗剪强度的影响权重,并应用了仿真单因素分析法研究了盐化作用对粘性土抗剪强度的影响规律。
According to uniform orthogonal design method, the soil samples with different salt content, water content and dry density were designed to be prepared by the use of three different factors and levels. Throughout test, the shearing strength is measured to saturated and unsaturated soil samples. The projec- tion pursuit regression （PPR） and one-factor analysis is applied to study the influence of salinization on shearing strength.
