Study on Micro-Structure Rebuild of Clay in Process of Consolidation
Vacuum freeze drying method is applied to prepare samples for SEM from one-dimensional consolidation clay which suffered different pressures from original remolded state. And then simple and synthetical micro-structure parameters of SEM photos obtained from some section are studied to uncover relation between mechanics properties and micro-structure. The results tell us that the first principal component approximately linear increases with consolidation pressure. It is distinct that the synthetical parameters are superior to the simple parameters in construction soil mechanics relation because the former can reflect the whole micro-structure qualities, but the latter can not.
