摘要：
In this study, an experimental investigation of the interference effect of two closely spaced strip footings resting on the surface of a layered sand deposit was conducted through a number of laboratory scaled model tests. The influence of the footing's length and spacing ratio and the thickness of the first layer on the efficiency factor were examined. The results are presented in terms of efficiency factors, and their variation was computed with respect to the change in the spacing ratio between the two footings. The results revealed that the efficiency factor depended significantly on the upper layer's thickness and strength.
