Abstract

Abstract

Using micro-structure observation,instrusive mercury and mineral analyses of consolidation process of typical soft soil samples from the Pearl River Delta,it is quantitatively researched into the changing low of micro-parameters,such as the form of micropores,the pore-scale distribution,the directionality of particles,etc with variation of its consolidation loads.The results show that the pore-scale distribution,the directionality of particles,the compressibility and permeability of the silt soil are significantly changed by the consolidation loads.In the early consolidation,the soil is large pore-scale,disordered particles,large compression coefficient and permeability coefficient,which rapidly decrease with the increase of pressure.However,in the late consolidation,the pore-scale reduces,the directionality of particles increases obviously,compression coefficient and permeability coefficient are also smaller and change slowly.
- soft soil of the PRD,
- pore-scale distribution,
- directionality of particles,
- engineering properties
