Abstract: Due to the performance of embankment under the earthquake, relative displacement at both edges of the crest is very important for body cracks. It can be computed by dynamic analysis. In this way, response spectrum analysis and Rayleigh damping coefficient are dependent factors to dominant frequency. Based on the new technology using advanced programs to compute frequency, free vibration analysis as the basic technique and considering of different vibration modes is accessible. This research tried to evaluate the distribution of dominant frequencies for short embankment (H=30 meter) using Finite-Element Method (ANSYS 13). To evaluate of the frequency, elasticity modulus ratio and foundation depth ratio were the main objectives. Both were defined by the ratio between the embankment and foundation. As a result, maximum and minimum vertical displacements were located on both slopes, and maximum horizontal displacement was exposed at the crest. The dominant frequency increased as the modulus ratio decreased. In addition, dominant frequency decreased as the depth ratio increased. The impact of the modulus ratio to enhance frequency was greater than the depth ratio. In terms of contributing engineering, the amplitude of the dominant frequency (Hz) was finally optimized for modulus ratios (0.25-1.00) and depth ratios (0.1-1.00). For critical situation, modulus ratio was more than three, and the depth ratio was half of the unit. More research about medium embankment is recommended.
