Abstract :

In this paper, the vertical displacement of a non-homogenous embankment dam is investigated and evaluated in both static and dynamic states using FLAC software. In this regard, initially, the results obtained from this software are validated against the results of conventional methods. Subsequently, using FLAC software and 100 selected models, the impact of important dam parameters such as crest and core height on the vertical displacement of the dam is studied under various conditions in both static and dynamic states. The data analysis approach in this work involves considering a parameter as a witness. The witness parameter remains constant, and assuming that it does not participate in the analysis, one effective parameter and one criterion parameter are chosen for discussion and examination. For example, if the dam base is chosen as the witness parameter, and its value is intended to be 165 meters, the results have shown that an increase in the height of the earth dam leads to an increase in vertical displacements under static and dynamic loadings.
