Abstract: 
Abstract: There is a worldwide interest in the proper design of embankment darns to ‎resist earthquake loadings. For the first time in Iran, a complete ambient vibration ‎survey due to low-level loads such as wind, machinery activities, low level tectonic ‎activities, and water exit from bottom outlet was performed on Marun embankment ‎dam. These kinds of ambient vibration tests are suitable for manifesting the lower ‎vibration modes of the dam body. Using different signal processing methods such as ‎Power Spectra Density, the results of in-situ tests have been used to evaluate the ‎natural frequencies, mode shapes and modal damping of the dam body. Besides ‎ambient vibration tests, the 3-D modal analysis of the dam body was performed using ‎ANSYS software. The foundation and abutment flexibility effects on dynamic ‎characteristics of the dam body were investigated and the dynamic soil properties ‎were used from Engineer s report and some empirical relations. Also initial shear ‎modulus of the dam body and foundation materials was evaluated by refraction ‎survey. In this paper, the test procedures, related signal processing results, numerical ‎analysis results and its comparison with the dynamic characteristics of the dam body ‎obtained from the full-scale dynamic tests will be presented Finally, calibrating ‎procedures of the numerical model (based on increasing the accuracy of dam body ‎geometry, soil and rock material parameters and foundation and abutment flexibility) ‎will be discussed‏.‏
