An Approach of Seepage Analysis Through Earth Dams Considering the Uncertainties of Soil Hydraulic Conductivity
This study focuses on an approach for analyzing seepage mechanism through earth dams whose soil hydraulic conductivities are considered as random variables. The approach employs finite element analysis integrated into a popular software for seepage consideration and an easy-to-implement algorithm for the random field generation. Hence, a Monte Carlo method is used for the further analysis. Based on the analysis of the outcomes, there are three aspects that need to be warned when using this method. Firstly, the correct algorithm of the random number generation leads the relevant observed frequency distributions to normal-distribution shapes. Secondly, the refinement of mesh can lead to more accurate results in terms of numerical issues but that can change the scale of fluctuation of random field. Finally, a number of 500 samples for a Monte Carlo simulation is acceptable.
