“…After that, the lateral displacement will decrease at a very low rate. The vibration constant is not changed in the total period of vibration; the lateral displacement of the top due to vibration is a value of 7 mm when the amplitude is 25 kPa and it has exceeded the lateral displacement according to the active state of soil [12] from this Figure, it can be found that the most dangerous is only in few minutes due to the author believes that this curve well level of at some quantity near 7mm. after that the lateral displacement for amplitude is 40 kPa will decrease and the vibration same constant and it start the change in 4 sec in very low rate to some quantity near 8 mm at time 15 sec.…”

“…The natural frequency of foundation vibrations has increased concerning embedment depth, but their amplitude has decreased. Several types of foundations, such as pile groups surrounded with grout, quay walls, circular tunnels, and disconnected piles under different intensities of earthquakes, were analyzed using PLAXIS software [10][11][12][13][14][15]. In this study, the effect of machine foundation has several frequencies on the performance of retaining wall and backfill material using PLAXIS software.…”

The dynamic reaction of the natural type of retaining wall is quite complex. Wall development and pressure rely upon the reaction of the soil underneath a retaining wall and the reaction of the backfill. The greater part of the present knowledge of the dynamic reaction of the wall has originated from the model test and numerical analysis. This paper aims to know the behavior of the retaining wall and the backfill. Also, under the effect of machine foundation, numerical modeling is used concerning a method of finite element. Two amplitudes of machine foundation subjected to three frequencies were used. The model used in the finite element was the linear elastic model (LE) for foundation and the Mohr-Coulomb model (MC) for soil. The results of this analysis for the amplitude of 25 kPa, the lateral displacement was 75% more than the active for the case of the amplitude of 40 kPa, the lateral displacement was 125% more than the active, and for the case of the velocity of 30 mm /sec very far higher than the maximum permissible velocity is 2.5 mm/sec and the acceleration was decreased by 52% between machine foundation and retaining wall.

Recent years have seen an increase in the use of computer-based numerical models to test the stability of earth dams and to simulate the impact of all the factors that affect their safety. Geo-Studio software and its sub-programs SLOPE/W, and QUAKE/W are used to determine the factors of safety and stability of dams, and investigations of dynamic analysis, a finite element serves as its base to do the numerical modeling for this study. The Hemrin Dam represents the case study and is regarded as the study's major focus. The results showed that the values of the safety factor increased from (1.439) to (1.583) when the water level is 8m, from (1.365) to (1.549) when the water level is 16 m, and from (1.084) to (1.317) maximum water level is 32m, without and with a vertical drainage column, because the pore water pressure is reduced and the effective stress is increased. In the case of a Rapid drawdown of water when a vertical drainage column is added, the value of the factor of safety decreases from 1.371 to 1.306 for the initial time, while decreasing from 1.406 to 1.363 for the second day of rapid drawdown. These reductions result from there is a delay between the process of the reservoirs' water level dropping and the water level lowering on the earthen dam's side. The vertical drainage column is crucial for the stability of the dam as the water is drained using the existing vertical and horizontal filters which eventually improve and increase the value of the effective stress.
