Numerical modeling of TANGAB dam under dynamic modeling

The study of the stability of the earth dams in the field of earthquake is one of the most complex issues because of the variation of the effects of the earthquake characteristics (in terms of intensity, acceleration, frequency, effective performance time), fill material various properties (soil resistance factors and porosity pressure) and change of properties mentioned in the effect of seismic loads caused by the earthquake. Given the effect of earthquake force and sudden changes in cavernous pressure, the points of the dam that are in contact with water are strongly affected by the loss of effective stress in horizontal and vertical directions. Dam crest also has a negative displacement over time that is facing downwards. Therefore, a more precise modeling of the input stimulus is necessary to obtain more accurate results
