ABSTRACT
In this study, the soil bearing capacity improvement using geobags is investigated. The bearing capacities of shallow foundations on reinforced and unreinforced soil under vertical loads are determined experimentally and numerically. Different sizes of geobags, as well as number and arrangement of geobags, were used in physical models and the load-settlement curves have been obtained. In the next step, laboratory conditions were simulated employing a 3D finite element computer code. Having validated the numerical modeling, the influence of other factors such as the scale effect on soil improvement and failure mode under a footing are investigated. Results of this study show that using geobags under footings significantly increases the bearing capacity of foundation. It was also found that the number and arrangement of geobags are the most important factors in the increase of bearing capacity and decrease of settlements of foundations.
Conclusion
The results of this study can be summarized briefly as follows:
1. External force induced a tensile force in bags and this leads to soil confinement and therefore increases te compressive strength of soil reinforced using geobags.
2. Improvement using geobags leads to reduce the settlement of foundation.
3. Increasing the number of geobags causes increase in bearing capacity of foundation.
4. Arrangement of geobags under the foundation is an important factor in soil improvement.
