摘要

En 中文

Experimental and theoretical investigations are carried out on a strip-footing resting on laterally confined subgrade by vertical grouted diaphragm wall as a vertical reinforced element. Loading tests on model footing reinforced via grouted diaphragm wall are performed to investigate the suitable dimensions of grouted wall to be injected along each side of the existing footing. The effects of width and depth of the grouted wall on the bearing capacity are studied. The bearing capacity of confined subgrade is clearly increased and the failure mode is modified. This technique is considered to be a suitable method to control the horizontal and vertical movements of the subgrade. (C) 2016 Faculty of Engineering, Alexandria University.
