摘要：
A behavior of the seepage flow through a uniform earth-fill dam constructed on a limited-depth permeable foundation and provided with a cut-off wall has been studied, and effective counter-seepage arrangements within the dam foundation were developed. The studies were conducted by using an electro-hydrodynamic analogy (EHDA) method for various cut-off wall design schemes, including impervious diaphragms, inverted filters, etc. Based on the obtained experimental data, advantages and disadvantages of various counter-seepage schemes were established, and engineering recommendations were developed to increase the seepage safety and performance reliability of earth-fill dams with cut-off walls formed on permeable foundations. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
