An Analysis of Seepage Mechanism Through Embankment Dams Based on the Assumption of the Uncertainties of Soil Permeabilities
摘要
This study is an attempt to investigate the unconfined steady-state seepage through embankment dams using the finite element method. The implementation is made employing a programming language (Python), which includes the random generation of soil permeabilities within the region of interest. Besides, the seepage also incorporates the effect of unsaturation into permeability using van Genuchten’s theory. Next, Monte-Carlo simulations are conducted to examine the aspects such as the relationship of the number of samples and the outcomes, statistical inferences of flowrates, exit gradient, positions of free surfaces within dam body.
