潮汐环境堆填引起超孔隙水压力消散研究

In the process of reinforcing soft soil foundation by preloading, excess pore pressure caused by preloading dissipate with the consolidation of soil. Based on Biot consolidation theory，combined with a certain project, a three-dimensional FEM model was established, the process of the consolidation of soil was simulated. On the ground of the former result, changes of excess pore pressure in the process of soil consolidation was analyzed, and the degree of consolidation under stress was computerized. During the study, the tidal environment of coastal area and the change of permeability coefficient following the change of void ratio of soil in the process of consolidation were considered, Mandaer effect was verified.
