Study On Seepage - Deformation Analysis Of Unsaturated Soil

The unsaturated seepage problem of soil, Calculation of earth rock dams, dikes, excavation.seepage control. seepage field and stress field of the mutual influence and interaction, is very important for soil mechanics and geotechnical engineering problems in. Study on non saturated soil in China started late, the lack of a complete theory for practice, In the soil seepage and stress strain analysis, without proper cons-ideration of the seepage of unsaturated soil is not possible simulation analysis, ignoring the influence of matric suction on the unsaturated soil, soil deformation and stability obtained with the actual situation to exist certain difference. And at present a lot of earth rock dam, embankment engineering In safety analysis, less likely to consider the influence of unsaturated soil seepage and coupling of seepage field, stress field effect.In this paper, based on the results of previous studies, Research and discussion of the unsaturated soil seepage theory, the unsaturated soil water characteristic curve, the permeability coefficient of the soil function,unsaturated soil seepage finite element equations, coupling calcuation of stress, Research and discussion of the saturated unsaturated seepage calculation of steady state and transient finite element analysis of embankment filling, coupled consolidation of soft soil foundation, the clay core wall dam completion period of layered stress deformation analysis, storage period of seepage field and stress field analysis on stress and deformation of the coupling effect.
