Foundations bearing capacity subjected to seepage by the kinematic approach of the limit analysis

Mehdi VEISKARAMI, Ghasem HABIBAGAHI

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 4,   Pages 446-455 doi: 10.1007/s11709-013-0227-5

Abstract: An estimate of the ultimate load on foundations on soil layers subject to groundwater flow has been presentedThe kinematic approach of the limit analysis was employed to find the upper-bound limit of the bearingcapacity.It was found that the bearing capacity has a decreasing trend with increase in the groundwater flow gradientand hence, a reduction factor has been introduced to the third term in the bearing capacity equation
