The transient swelling process of polymeric gels is studied and a finite element model is introduced to simulate the phenomena based on existing hyperelastic theory for inhomogeneous swelling of gels and analogies made to transient heat conduction analysis. Examples of free swelling of a cube and a fixed cylinder were investigated, showing the highly non-linear deformation present during transition from the initial state to equilibrium.
Landslide is common geological hazards to the hydropower reservoir. Reasonable parameters are the key to design and prevent the landslide. After geological exploration, a few laboratory tests (uniaxial compression test, unsaturated permeability test, unsaturated direct-shear test) were conducted for the sliding mass. In order to obtain reasonable strength parameters of sliding mass, basing on the experimental results, some researches (such as engineering analogy, parametric inversion) were performed by using limit equilibrium method. The mechanical parameters of the slope were proposed.
