| Abstract: | An analytical method for prefabricated vertical drain (PVD) improved subsoil.is introduced. A concept of equivalent vertical hydraulic conductivity of PVD-improved subsoil with its calculation method was proposed. Then, the determination of parameters is introduced. Finally, the proposed method is applied to an engineering example. The results show that the proposed method can predict the measured data very well. |
| Keywords: | prdfabricaled vertical drain (PVD) soft subsoil equivalent vertical permeability engineering example |
