ABSTRACT
The paper reports an experimental and theoretical investigation into bearing capacity of stable
loaded strip-footing resting on laterally confined subgrade by vertical grouting diaphragm
wall as a vertical reinforced element. The main notions of this paper to more understand how
to strengthening of the subgrade layer under shallow existing footing on sand and mitigation
the settlement. Loading tests on model footing reinforced by grouted diaphragm wall were
carried out to investigate the suitable dimensions of grouted wall to be injected along each
side of the model footing. The effect of width and depth of the grouted wall on the bearing
capacity failure and confined subgrade were explained. The results show that the bearing
capacity of reinforced subgrade clearly increased and the resulting bearing capacity failure
had modified. This technique was considered to be a good method to control the horizontal
movement of the subgrade and decreasing the vertical settlement.
