Abstract

The drainage consolidation method is widely used in the soft ground to increase its strength and decrease its deformation. One of the difficulties in the calculation of drainage consolidation is the simulation of the vertical drains. The common method is the equivalent transferring method from the axial-symmetric sand well to the plane-strain sand wall based on the equal degree of consolidation at various stages. Because the corresponding point-to point relationship would be lost during this transformation, it is impossible to predict the horizontal displacement and pore pressure accurately. From the macro-view, the installation of vertical drains acts as the improvement of the permeability of the ground or the acceleration of the seepage of the pore water. Therefore, the equivalent permeability method or the method treating the well as drainage function is preferred to be recommended.
