摘要
The permeability characteristics of natural soft clays and corresponding remolded clays were investigated in laboratory. The results show that at the same void ratio, the permeability of undisturbed soil is greater than that of the corresponding remolded clay. The coefficient of permeability is almost the same for remolded soils with the same remolding method and different initial water contents. Even if void ratio is the same, the coefficient of permeability is different due to different ways of remolding. Void ratio and fabric are necessarily considered for determining the coefficient of permeability of clays.
