| Abstract: | By using the osmotic oedometer and modifying the K0 consolidometer,the combined determination of osmosis and consolidation on Shanghai natural soil,remolded soil and silty clay samples are carried out.The comparative analysis is made on the deformation and permeability of Shanghai soft soil under different loads and water heads.According the vertical and horizontal e-k curves of the soft clay,the expression for the permeability coefficient and the void ratio is fit out.The tests indicate that,the structural... |
