Abstract :Under the repeated loads of the soil, stress-strain and strength properties play an important role in solving the engineering problems. The stresses-deformation and strength properties of the soils under repeated loads, which are caused by the depression, are changing. As a result, deformations occur in the ground and structural damage occurs. Engineering properties must be known in order to minimize the damage of earthquakes. One of these parameters is an important factor in the effects of frequency earthquakes. In this study, the effects of frequencies obtained from different earthquakes on the dynamic characteristics of the ground were investigated. In the study, a dynamic triaxial test set was used to investigate the dynamic properties of soils. The variation of dynamic properties under the experimental conditions was investigated by loading with regular and irregular frequencies on the sand samples.
