Abstract

Earth dams’ failure may occur due to different reasons such as structural instability conditions, hydraulic conditions, seepage through dam body, and/or rapid drawdown. The determination of factor of safety for the dam slope stability under different cases of operations is vital to ascertain the dam overall safety. In this study, Finite Element modelling is used to simulate seepage and slope stability analysis of earth dam problems using GeoStudio software. The model is verified by the practical implementation of the dam. Then, it is used to analyse seepage and stability of Prototype earth fill dam in Banha University. The Bishop analytical method is used to assess the stability of the dam side slopes. The results of the analysis presented in this thesis confirm the safety of earthfill dam against combined seepage and slope stability under all the normal and failure cases during the operation. Seepage analysis and Stability Investigation are very important issues, which should be considered in designing.
