Investigation of the Effect of Different Approaches in Predicting the Surface Response of Dynamic Behavior in Low Plasticitiy Clay Soils

The dynamic behavior of soft soils constitutes a critical area of geotechnical engineering and earthquake engineering. The aim of the study is to investigate the effect of different approaches in predicting the surface response of dynamic behavior in soft soils. The change of soil properties under dynamic loads is investigated by finite element models. The dynamic behavior of soft soil samples modeled as one dimensional (1D) and two dimensional (2D) was investigated using PLAXIS and DEEPSOIL software. To reveal the effects of 1D and 2D approaches on the surface response, various parameters were analyzed in detail. The variations in the surface response with the changes in soil properties was obtained and it was seen that the soil properties is a critical factor in the accurate prediction of the surface response. The results also showed that the model dimension should be taken into account in predicting the dynamic behavior in soft soils and that this effect is important both in modeling approaches and in engineering solutions in the field. These findings provide important data that will contribute to the safer and more accurate implementations of geotechnical designs.
