One of the excavation stability methods is the use of a reinforced concrete piles system. In grounds with loose soil, the penetration amount of the pile tip in condensed soil, is one of the determinant parameters of pile stability. In this research, the influence of pile penetration length in dense soil (dense sand) by changing soil layering and also by applying acceleration mapping of two earthquakes, Ahar-Varzghan (2013) and Bam (2003), has been investigated using Plexis software. The results show that with the increase in the loose soil depth in the mentioned earthquakes, in addition to the increase in the bending moment, the horizontal deformations in the static and dynamic states compared to the base model are 18 and 6 times, respectively, and the vertical deformations in the static and dynamic states compared to the base model are 48 and 6 times, respectively, and the total deformations in the static and dynamic models compared to the base model increase by 18 and 7 times, respectively. Rupture in the pit occurs when the depth of loose soil reaches 9 meters.
