WebThe bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil. Ultimate bearing capacity (q f ) is the theoretical maximum pressure which can be supported without failure; allowable bearing capacity (q a ) is the ultimate bearing capacity divided by a factor of … http://duts.petra.ac.id/index.php/duts/article/download/186/160/601 WebWhere = unit weight of soil, Df = depth of foundation. 3.
