Abstract

Water molecules flow through the porous soil environment due to potential energy. Leaking is always one of the important topics in dam design. Due to the presence of cavities among the soil grain solids, it is possible to move water in the soil mass that may endanger the stability of the dam, so the effects of this movement should be considered. In this research, which uses a nonlinear permeability function, the water escaping dimming elements include a seal wall in the core axis; a seal wall in heel; a seal wall in heel and paw; a clay blanket with variable thickness and length; the combination of two seal walls, one on the axis and the other on the heel, the combination of clay blanket with variable thickness and length along with a seal wall in the core axis, which is compared to the non-sealing state due to the most important effective factors in leaking, including Debi, velocity, and gradient in Bashar's zoned dam. The Geo-Studio software is used and hydraulic tilt changes are also considered at the core of the dam.
