The current research uses a physical model to investigate the role of micropiles as vertical reinforcement of footing when embedded in sandy silty soil from Mosul City – Northern Iraq. The experimental program focused on carrying out several load-settlement tests for the footing with two different reinforcement conditions: by a single micropile and group micropiles. The study is extended to investigate the role of soil homogeneity, weak soil underneath by strong soil layer, in the behavior of load-settlement curves for the reinforced footing. Next, the load settlement tests were, again, conducted using the same model but for the non-reinforced footing (flat footing). The first results indicated that the physical model has succeeded in representing all the studied cases. Also, the results showed a significant improvement in the behavior of the load-settlement curves when the footing was reinforced with micropile, especially using the micropile group, compared with the non-reinforced footing. Also, the degree of improvements in the load-bearing capacity and load-settlement behavior, for the footing reinforced with micropiles embedded in different conditions of soil homogeneity, was examined through two different non-dimensional factors: bearing capacity ratio (BCR) and percent of settlement reduction (PSR). The results indicated that the BCR was increased and the PSR was decreased for the reinforced footing compared to the non-reinforced footing. Moreover, from the test results, we noticed that the homogeneity of the soil has a significant effect on the load-settlement curves behavior of the footing.
