Investigation of the effect of Hammer radius parameters and number of impact on soil improvement by dynamic density method In line with the construction of offshore structures

There is a different method for increasing the resistance and quality of engineering of soils, one of the most suitable ones is dynamic compaction. In this method, weights are released from the specified height and, as a result of collision with the ground, the soil will be compacted. In this research, field experiments were initially initiated. Then using the results obtained in this section, the soil dynamic compaction was modeled. In order to do the modeling, the present study was conducted using FLAC two-dimensional software. Due to the implementation of various designs in the city of Abadan, the area was selected as the site of the project After field experiments, mechanical properties of the soil were extracted and then modeled with the definition of test patterns. The result of this research show that For all conditions of modeling, the maximum deformation of soil was observed in the hammer Cutoff area, which decreased in depth of soil. Also, the results indicate that effective stress in soil under dynamic density decreases with increasing depth.
