| dc.description.abstract | The Ajima Dam is located mainly at Kita alegn Kebele, Angolelana tera Woreda of North Shewa Zone in the Amhara Region. At an altitude of about 2806m a.m.s.l, with 45.5 m height and dam crest length of 377m. Although dams are so much important, their overall construction cost is high. In order to reduce this challenge, this study is intended to incorporate reinforced geotextile in part of the dam region. This technique is used to decrease the construction cost with decreasing the required construction period. Geo-synthetics Materials are presently used widely in international dam construction practice as impermeable elements, filters, drains, reinforcing and separating members, and for protecting and reverting slopes of earth dams. The stability analysis has been done by using limit equilibrium method. The analysis is conducted for three different slope options using geo slope 2007. After generating the result the more stabilized and economical one slope is taken. Reinforced geotextile has been laid with horizontal layers with different length and spacing depending on the slope. The safety factor were increased from the previous in the same in situ material for the reinforced geotextile. Beside to this the construction cost is decreased by 29.83% with the planned construction period. | en_US |
