Abstract:This study aimed to evaluate the safety of dump slopes in high-altitude areas subjected to severe dry-wet cycles. The in-service dump slopes No.1 and No.2 of the cement-used limestone mine in a high-altitude mining area were investigated. Based on the unsaturated-saturated seepage theory, incorporating the unsaturated soil shear strength equation and the matrix suction distribution equation, numerical calculations have been conducted to assess the evolution characteristics of the unsaturated-saturated seepage … Show more
