Other Abstract



Based on concrete plastic-damage model, a three-dimensional numerical calculation model of permeable dam is established. According to the theory of single factor, the chang rules with the depth-width ratio, number, opening ratio and position of drain holes for the maximum tensile stress and Mises equivalent stress near the permeable dam drain hole and dam toe are revealed through numerical simulation. Finally, how to withstand the ultimate impacting load for a permeable dam is studied. The results show that the maximum tensile stress decreases firstly, and then increases with the increasing of depth-width ratio, remains little changing with the increasing of opening ratio and number of holes and decreases with the increasing of vertical distance; Mises equivalent stress decreases firstly, and then increases with the increasing of depth-width ratio, decreases with the increasing of vertical distance, increases with the increasing of o-pening ratio, and remains little changing with the increasing of the number of holes; drain hole reduces the tensile strength of the permeable dam and with the increasing of opening ratio,the maximum impact force of debris flow on the permeable dam will reduce. Research results can provide a theoretical guidance on structural design and optimization for permeable dams.
