Design of an Embankment Dam is a crucial issue from the view point of safety and economy ofrnconstruction cost. Asphaltic concrete core is virtually impervious, flexible, resistant to erosion andrnaging, workable and compactable and offers joint less core construction. It is very well suited forrndams in earthquake regions and best suited when there is no ample supply of impervious materialrnwithin economically feasible distance.rnIn Middle Awash high embankment dam, due to biggest challenge is the hauling distance of thernimpervious clay core material, the choice of rock fill asphalt concrete core dam is the most suitablernamong alternatives emphasis was placed on costs, severe weather conditions during construction,rnearthquake resistance, and compatibility with the geological conditions which might causernsignificant differential settlements across the valley.rnThe paper provides modeling of the dam cross section for rock fill central asphalt concrete corerndam design using Geo-studio 2007 Software and computing factor of safety for upstream andrndownstream slope stability for all different loading condition before and after earth quake usingrnlimit equilibrium method and finite element method. Static and pseudo-static analyses have beenrnconducted in SLOPE/W 2007 using limit equilibrium method. For rigorous dynamic analysisrnEquivalent Linear Dynamic analyses have been done using QUAKE/W 2007 module.rnBased on recommended design standards such as: - ICOLD Bulletin, USBR, USACE and otherrncited reference material the design and analysis of Middle Awash Multipurpose Dam wasrnconducted using Geo-studio 2007 software products and the result meets the recommended rangernof design standard.rnKEYWORDS: Asphaltic Concrete Core, Geo-studio 2007, Design of embankment dam, MiddlernAwash Multipurpose Dam, Slope stability Analysis, Pseudo-static analyses, Equivalent LinearrnDynamic
