【 摘 要 】

Due to the high plasticity index and low permeability of reclaimed ground composed of dredged soil, the reinforcement period is very long, which makes the merits of vacuum preloading, short reinforcement time, disappear. Surcharge preloading method becomes the most suitable and economic way. The equivalent permeability method is used to simulate the installation of the plastic vertical drain and the influence of different permeabilities, namely the interval space is calculated numerically.
