QUESTION 3 A concrete pile is driven into top two layers of subsoil strata made of 10m and 5m thick saturated clays respectively. The pile's diameter is 500 mm throughout the pile. Determine the allowable bearing capacity of the pile. The subsoil properties are shown. (Answer 454 kN). Clay layer 1: Saturated unit weight of clay = 18KN/m3 %3D Average undrained shear strength = 100kPa, q = 0 Adhesion factor = 0.48 Clay layer 2: Saturated unit weight of clay = 19kN/m3 %3D Average undrained shear strength = 120kPa, q = 0 %3D Adhesion factor = 0.42, No = 9.

QUESTION 3
A concrete pile is driven into top two layers of subsoil strata made of 10m
and 5m thick saturated clays respectively. The pile's diameter is 500 mm
throughout the pile. Determine the allowable bearing capacity of the pile.
The subsoil properties are shown. (Answer 454 kN).
Clay layer 1:
Saturated unit weight of clay = 18kN/m3
Average undrained shear strength = 100kPa, o = 0
%3D
Adhesion factor = 0.48
Clay layer 2:
Saturated unit weight of clay = 19kN/m3
Average undrained shear strength = 120kPa, q = 0
Adhesion factor = 0.42, Nc = 9.
