Abstract

The PSEUDO-static analysis is one of the conventional methods in EMBANKMENT DAMS design and International Commission on Large Dams (ICOLD) suggests using this method before ultimate dynamic analyses. In this research, the static, PSEUDO-static and DYNAMIC ANALYSIS of Masjed Soleyman embankment dam have been performed. Using dynamic and PSEUDO-static analyses results, the safety factor of critical sliding surface were calculated. Permanent displacements of critical sliding surface were evaluated by Newmark method and the calculated safety factor was compared. Based on the comparison results in different water levels of the reservoir and by introducing a new equation, the variable HORIZONTAL ACCELERATION COEFFICIENTS in height of the dam body were calculated. Finally, obtained HORIZONTAL ACCELERATION COEFFICIENTS were compared with other criteria introduced in different embankment dam's design codes. Totally, the results indicate that the proposed method leads to a larger horizontal acceleration coefficient in higher parts of the dam body.
