摘　　要：在正交实验设计的基础上,对粘土吸附离子的力学特性进行了室内实验研究.结果表明:粘土的塑性指数基本随吸附离子含量的增大而增大;在单离子的情况下,离子浓度与土的塑性指数之间表现出良好的线性关系.On the basis of the orthogonal design, the mechanical characters of clay adsorbed metal cation are analyzed by large amount of lab experiments. These results indicate that the plasticity index of clay is basically in- creasing with the growing of the content of adsorbed metal cation. In the case of single metal Cation, the relation- ship between the concentration of metal cation and the plasticity index shows a good linear relationship.
