Abstract
Analysis of seepage and stability is considered as an important case in designing which today, with
advanced numeric software acceptable results will be obtained before and after Construction. In the
present study, the behavior of earth dam against effective factors was investigated by software
Ansys12. The studied dam is Maroun soil dam, which is located in 19Km north of Behbehan and
constructed on Maroun River. This dam is soil- gravely dam. It was tried in this research that stability
of dam be evaluated by finite element method and Ansys software, and then compare by software
results like Geo-studio. At first Following, the stability of dam slope was considered and the behavior
of dam was stimulated by several methods and there were relatively same results for the amount of
safety factor and unstable surface. Safety factor was 4.21 for upstream by bishop method in Ansys and
4.71 in Geo-studio and for downstream 1.5, 1.8, respectively. Finally, the maximum and minimum
amount of tension was determined by analyzing tension, strain and movement and the areas with
different sediments and possible cracking and subside regions were determined. In this part, both
softwares provided relatively same results and the maximum amount of movement in dam estimated
5-6 meters. However, both softwares are best ones in analyzing and finite method and completely
correct introducing of current conditions could have acceptable analyses.
