Topic: INTERFERENCE OF ADJACENT FOUNDATIONS DUE TO DIFFERENT LOADS, SHAPES AND DEPTHS
Abstract: This study is mainly concerned with the effect of interference of adjacent foundations due to different loads, shapes and depths. Three pairs of wooden plate will be tested with different shapes, loads applied and depths. The settlement of soil will be observed through this study. The results obtained from the laboratory test will be compared with the theoretical results using Terzaghi’s bearing equation. The proximity of footings on sand enhances the responses of foundations both in terms of settlement and ultimate bearing capacity. For two foundations in proximity, the settlement will be increasing due to increasing of interference. Besides that, the ultimate bearing capacity of interfering foundations decreases with increase in spacing. For square footings the maximum increase in ultimate bearing capacity should be about 40% greater than that of the isolated footing. In the case of circular footings an enhancement in bearing capacity of footing is about 58%.
