In this study, several methods have been experimentally evaluated to increase the efficiency of reinforcements in the bearing capacity of a strip footing on sand. The capacity of the foundation in five different configurations including single and multilayer reinforcements was evaluated with free and wraparound anchored end, different thickness, and nailed with different numbers of nails and patterns. According to the results of these tests, dividing the length of the reinforcement and using it in more layers increases the efficiency of the reinforcement, but this division of the length of the reinforcement has a certain limit that reducing this limit reduces the efficiency. The use of wraparound anchorage caused more interaction between the soil grains and the reinforcement surface and as a result increased the bearing capacity of the foundation. Increasing the thickness of the reinforcements was another parameter studied in this study. Increasing the thickness of the reinforcement caused the bearing capacity to increase. The results of the experiments show that the pattern of nails has a significant effect on the performance of the reinforced soil.
