| description | The use of wrapping geosystems such as soilbags as reinforcement has been increasingly studied. Soilbag columns may be utilized as an alternative method for improving the weak soil under the footing. An analytical approach was developed to predict the stress-strain response of the soilbags under compression. Using three-dimensional numerical modeling, the validity of the relationships was investigated and then developed for the soilbag columns supporting the footing loads. Compared to numerical results, it was found that for the stiffer wrapping materials, the analytical approach overestimates the bearing stress of the soilbag columns. However, the estimation of the bearing stress of soilbag columns matches well with the numerical results for high values of backfill friction angles. The results from the analyses were used to develop the design guidelines for the design of soilbag columns for the given settlement. Design charts propose a preliminary selection for the tensile stiffness of wrapping geosystems. |
