“…For two closely space strip footings, loaded to failure simultaneously at the same magnitudes of failure loads, there are quite a few research investigations available in literature (Stuart 1962;West and Stuart 1965;Saran and Agarwal 1974;Das and Larbi-Cherif 1983;Kumar and Saran 2003;Kumar and Ghosh 2007;Kumar and Kouzer 2008;Kumar and Bhoi 2009) to determine the effect of interference on the ultimate bearing capacity of the foundation. Stuart (1962) has theoretically studied the interference effect of two strip footings on their ultimate bearing capacity.…”

“…By using the limit equilibrium method, he examined the variation of the ultimate bearing capacity with respect to change in the spacing between the two footings. The effect of the spacing of two rough strip footings on their ultimate bearing capacity was also studied by Kumar and Ghosh (2007) by using the method of characteristics. Kumar and Kouzer (2008), by using an upper bound finite element limit analysis, examined the interference effect of two footings in a rigorous manner.…”

“…1, in which the failure surface is assumed to pass through the toe of the slurry trench. The log-spiral slip surface is used for problems of slope stability (Chen et al, 2003;Loukidis et al, 2003;Zhu et al, 2003;Jiang et al, 2009) and foundation stability (Kumar and Ghosh, 2007;Han et al, 2012b). The region ABC rotates as a rigid body around the center of rotation O with the materials below the logarithmic surface AC remaining at rest.…”

A 2D and 3D kinematically admissible rotational failure mechanism is presented for homogeneous slurry trenches in frictional/cohesive soils. Analytical approaches are derived to obtain the upper bounds on slurry trench stability in the strict framework of limit analysis. It is shown that the factor of safety from a 3D analysis will be greater than that from a 2D analysis. Compared with the limit equilibrium method, the limit analysis method yields an unconservative estimate on the safety factors. A set of examples are presented in a wide range of parameters for 2D and 3D homogeneous slurry trenches. The factor of safety increases with increasing slurry and soil bulk density ratio, cohesion, friction angle, and with decreasing slurry level depth and trench depth ratio, trench width and depth ratio. It is convenient to assess the safety for the homogeneous slurry trenches in practical applications.

“…As a result, the bearing capacity of such foundations is affected by their adjacent foundations. The ultimate bearing capacity of two interfering strip footings resting on soils was studied theoretically [1][2][3][4]. Results of these studies show that when two strip footings approached closely enough, failure zones beneath the footings affect each other and ultimate bearing capacity significantly increased.…”
