Abstract: For an actual project, the reason of standard ultimate bearing capacity of a single pile less than that of designing value is analyzed. It is suggested that when kaolin included in the soil at the end of piles is softened by water, a plastic shear-sliding plane will be generated. Then the soil will be in shear failure mode under static loading which significantly decreases the soil standard ultimate bearing capacity. For this case, it is not reasonable to determine the soil standard ultimate bearing capacity only by liquid index based on technical code for building pile foundations, the compression modulus and ratio of pore should be added for consideration.

Key words: liquid index, standard ultimate bearing capacity, plastic shear sliding plane, local shear failure
