Analysis of Earth Dam: Seepage and Stability Using Ansys and Geo-Studio Software

Abstract

Abstract: Seepage analysis and Stability Investigation Is very import issues that should be considered at designing. Now Ansys, very acceptable and powerful software are created for Analysis. In this study, behavior of soil Dam: with different effective parameters, have been studied. The case Study (study Dam) is maroon soil Dam which is located: 19 kilometer North of Bahaman, on maroon river This Dam is Rock-soil Dam. In this research, it has been attempt soil stability of Dam has been done with using Ansys. Therefore, result wore compared whit Geo studio Software result. Firstly, Dam were studied with using there Analysis method, then seepage are predicated the seepage Rate in Ansys, 18 % percent is lower than Geo studio results. Besides, Slope Stability is studied and different behavior of Dam is simulated. The Results are almost at similar Range for Slope Stability result. But Safety factor values (for two software) had distinctive difference. For instance calculated safety factor, according to the Bishop method, for upstream slope 1, 2,4 and for Geo studio, value equal 1.5 are determinate. Finally, movement and maximum and minimum strain and stress are calculated with analysis method of stress and string and settlement around crack zone is determinate. In other words, maximum vertical movement is estimated around 6 meters. Key word: Soil dams Stability Finite element method Ansys
