ANALYSIS OF FOUNDATIONS ON REINFORCED SOILS
This paper demonstrates how a finite element model of reinforced earth can be used to investigate the increase in bearing capacity and stiffness of a foundation due to the placement of reinforcement in the soil. The finite element analysis is briefly summarized, and then used to examine the effect of reinforcement on the load-settlement behaviour of a strip foundation. It is shown that the improvement in foundation performance depends on both the number of reinforcing layers and on the concentration (surface area per unit width of footing) of the reinforcement. A footing on a reinforced soil mass overlying a cavity or a very soft zone is also analyzed, and the reinforced soil is shown to result in a significant improvement in footing performance. The results of the analyses are found to be in broad agreement with published model footing test data. (TRRL)
