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 presented. The kinematic approach of the limit analysis was employed to find the upper-bound limit of the bearing capacity. Both smooth and rough base strip foundations were considered associated with different collapse patterns. Presence of the groundwater flow leads to a non-symmetric collapse pattern, i.e., a weak side and a strong side in two-sided collapse patterns, depending on the direction of the flow. It was found that the bearing capacity has a decreasing trend with increase in the groundwater flow gradient and hence, a reduction factor has been introduced to the third term in the bearing capacity equation as a function of the flow gradient.

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 2,   Pages 237-245 doi: 10.15302/J-FASE-2017135

Abstract: Quantification of seepage in disconnected river-aquifer systems is significant for local water managementMFSL can calculate the stable seepage rate by assessing the dominant low permeability layers (includingWe used MFSL to calculate local seepage rate, and used GIS to extend the results to a regional scale.Results showed that low permeability liners could greatly reduce the seepage rate.However, if an unlined inundation area exists, the seepage rate may increase greatly.
