Alemdag, Selcuk
In this study, the bearing capacity and permeability of andesite and andesitic breccia rock masses, forming the basement for Gumustas waste dam, planned as a rock fill housing, were evaluated using various empirical equations and numerical analysis. The total stress constituting over the basement caused through ore waste building up in the body of dam and reservoir was determined by a finite element method. Then, this stress was compared with bearing capacities calculated for the rock masses. The permeability of rock masses in dam site and the lake were appraised with pressure water test experiments (Lugeon method), performed within opened bore holes and finite element method (seepage analysis). Since chemicals seeping from waste dams into the ground water are of vital importance for human health and the environment, the dam body must be made completely impervious using upstream slope and reservoir geosynthetics.

Gurocak, Zulfu; Alemdag, Selcuk
This study was performed in order to evaluate the permeability of the basalts and pyroclastics and the maximum depth of grout injection at the Atasu dam site, Turkey, using the equations of Kiraly and Hoek and Bray based on values obtained from Lugeon tests. In order to evaluate maximum discharge values and depth of injection, seepage analyses were performed using the finite element technique for each 10 m up to 100 m. The results indicate that to establish an impermeable zone at the dam site, the depth of injection should be taken as 50 m for the left and right slopes and 40 m for the river bed.
