|Abstract:||Design of an Embankment Dam is a crucial issue from the view point of safety and economy of construction cost. Asphaltic concrete core is virtually impervious, flexible, resistant to erosion and aging, workable and compactable and offers joint less core construction. It is very well suited for dams in earthquake regions and best suited when there is no ample supply of impervious material within economically feasible distance. In Middle Awash high embankment dam, due to biggest challenge is the hauling distance of the impervious clay core material, the choice of rock fill asphalt concrete core dam is the most suitable among alternatives emphasis was placed on costs, severe weather conditions during construction, earthquake resistance, and compatibility with the geological conditions which might cause significant differential settlements across the valley. The paper provides modeling of the dam cross section for rock fill central asphalt concrete core dam design using Geo-studio 2007 Software and computing factor of safety for upstream and downstream slope stability for all different loading condition before and after earth quake using limit equilibrium method and finite element method. Static and pseudo-static analyses have been conducted in SLOPE/W 2007 using limit equilibrium method. For rigorous dynamic analysis Equivalent Linear Dynamic analyses have been done using QUAKE/W 2007 module. Based on recommended design standards such as: - ICOLD Bulletin, USBR, USACE and other cited reference material the design and analysis of Middle Awash Multipurpose Dam was conducted using Geo-studio 2007 software products and the result meets the recommended range of design standard.|
