INFLUENCE OF HEAD ELEVATION ON THE STABILITY OF EARTH FILL DAM, FADA DAM AS A CASE STUDY
2015
Ali Laftah Abbas
In the present study, slope stability and seepage are analysis for Al-Fada dam. Two software's (Geo-Slope/w and SEEP/W) using Bishop method and finite element method are adopted for stability and seepage calculations, respectively. The usual procedure in the stability analysis of slopes is to calculate the safety factor of various assumed slip surfaces, and then to regard the slip surface having the smallest safety factor as critical. four cases of water level are consider in analysis of slope stability of dam. The final conclusion is the body of the dam and its foundation is safe for the effect of seepage through the dam and foundation, also the analysis of the results of this study showed that Al-Fada earth dam is safe against the danger of piping and slope sloughing under all case of water level.
