93AbstractSlope stability is the resistance of inclined surface to failure both in sliding or collapsingforms The main purpose of a slope stability analysis is to find endangered areas investigationof potential failure mechanisms determination of sensitivity of slope to different triggeringmechanisms designing of optimal slopes with regard to safety reliability and economics Successful design of a slope requires enough geological information and site and laboratorycharacterizations Measurements of soil rock properties beside establishing slope geometry considering groundwater conditions and also mapping discontinuity features and mechanismsare necessary In this study the effect of pore water pressure on the slope stability in the Gol e Gohar open pit mine is analyzed using a numerical finite difference method based codes FLAC3D and FLAC2D considering dry and saturated conditions The numerical slopestability analyses was performed on 9 two dimensional sections and also 2 three dimensionalmodels The results showed that in all sections the difference between the safety factor incompletely dry and saturated model is approximately 30 percent The maximum instability were found in the southern and western walls of the mine The difference between the resultsin two and three dimensions was not significant Two methods including reducing slopeinclination and also excavating drainage tunnel were examined in those endanger slopes Thesensitivity analysis was also performed in order to determine the exact location and size of thedrainage tunnel The results showed that the drainage tunnel must be excavated in the lowestheight and closest site to surface of bench When a slope was considered without any benches the overall safety factor was increased by 12 percent compared with the real condition whilethe failure mode did not changed remarkably
