Nonlinear consolidation of vertical drains with coupled radial‐vertical flow considering time and depth dependent vacuum pressure

Summary The system of vacuum pressure combined with vertical drains to accelerate soil consolidation is one of the most effective ground improvement methods. The consolidation theories of soft soil improved by vertical drains including void ratio–dependent compressibility and permeability have been...
