Study on Micro-Structure of Loess under one-Dimensional Consolidation

Abstract:

The SEM images were obtained from three different sections of the specimens which suffered to one-dimensional consolidation under 5 grade pressures. Basic micro-structure parameters were obtained from these SEM images and their relations with various consolidation pressures were studied. The result indicated that the particle area ratio increase with the increasing of consolidation pressure. Synthesis parameters were studied using principal component analysis. The result showed that the first principle component linearly increased with the increasing of consolidation pressure. When established soil mechanics relation, the Synthesis parameters of micro-structure can be used. That can reflect the integrated character of micro-structure of loess.
