| Abstract: | A large volume of analysis of grain size, aggregate components, pore size and distribution before and after consolidation, and micro-structure and pore solution composition and exchangeable cations of soft clay in Shanghai was conducted. The possible effect of the pore size variation with consolidation and artificial injection is discussed. And the effect of microscopic characteristics of soft clay on consolidation and deformation of soil mass is depicted from physico-chemical theory. At last, in this paper a new ideas of controll on consolidation and deformation of soft clay is presented. |
