Abstract

The microstructure porosities and pore size distribution of the clayey soil in the Pearl River Delta were studied by techniques of Scanning Electron Microscopy (SEM) and pressure gradient method. It was found that small pores were increased with increasing of the loading of clay samples. On the other hand, large pores with diameter of over 4 m were obviously decreased with increasing the loadings because of the squeeze effect to cause the large pores to be broken into smaller ones. The loading amount was investigated based on the stress change to improve the efficiency of saturated clayed soil foundation treatment. The effect of stress distribution on mechanical properties in the consolidation process was also investigated through the rate of anisotropy characteristics in the same full of saturated soft clay. The maximum principal stress and pore size with short axis angle were reduced.
