| 概要 |
An unreinforced sand bed and a geogrid-reinforced sand bed were both set over a group of floating stone columns in soft clay, and the results of a variety of computer models were compared and contrast...ed with the findings of an experiment. 3D-FEA simulations were carried out with the mechanical structural simulation software Ansys APDL (Version 18.2) for the goal of modeling the stone column structures made in soft clay/snad with or without support structure. This was done to get the desired result. When geogrid is submitted to a finite-element analysis, it is analyzed as though it were made of an elasto-plastic material. Because it was gathered from the immediate vicinity in Rajasthan, the stone that ended up being used for the simulation was considered to be an unnecessary byproduct of the production process. The choice to use the waste materials as column material for the stone was motivated by the desire to increase the level of sustainability achieved by the project. Both an unreinforced sand bed (USB) and a geogrid-reinforced sand bed (GRSB) may be thought of as having a critical thickness that was calculated using FEA simulation results and it was 20% to 30% of the footing diameter of the stone bed. When in present study thickness is increased beyond this point, there is only a marginal increase in the bearing capacity. In present study the settlement of the stone column was also studied and the proper analysis was performed to find the effect of the settlement on the stone column structure during facing the maximum load conditions. The role of the diameter of the stone column paly crucial role was concluded by the FEA study set for the present study. This yields the value for the ideal length of the group. When compared to the plastic strain that occurs in the geogrid planar sheet, the plastic strain that takes place in the material that makes up the stone column is far higher.続きを見る
