Comparision Experiment of Water Content Redution Methods of Engineering Soil

The natural drainage, vacuum drainage and electro-osmotic drainage are all proved to be feasible in theory. In order to distinguish the feasibility, the drainage methods are experimentized. The drainage efficiencies are all high at the beginning and the effectivenesses of all the methods, the reduction of water content and the improvement of the soil density are verified. The effect of electro-osmotic drainage is proved to be the best of all.
