【Abstract】 For levees on double layer foundation, adding weighting soil to the landside slope is an effective measures to prevent the foundation from seepage failure. A theoretical model is developed to determine the width and thickness of weighting soil layer, and a numerical method to solve this mode is introduced. The case study shows that the sizes of weighting soil layer given by this model is rational and economical.更多还原
