The Experiments Study and Theoretical Analyses on Piping and Flowsoil |
|
| Abstract: | This thesis mainly studies the mechanism of piping and flowsoil in four aspects which include concepts,experiments,finite elements analyses and analytic analyses.As a result,this study has gone beyond the present levels and do the antithetic and quantitative analyses.At the same time,this study takes into account the forming of the flowsoil channel and the effects on the underground water seeping that it brings.So this study can simulate the flowsoil process from the beginning to the ruin.And the experiments data has proved that finite elements model and analytic resolution are practical and perfect. |
| Keywords: | piping flowsoil analytic resolution sand model finite elements method |
