Document Summary
The settlement at the top of pile can be broken down into three components: (1) settlement due to axial deformation of pile shaft; sa. Qp = point load transmitted to the pile tip in the working stress range. Qs = shaft friction load transmitted by the pile in the working stress range (in force units) S = 0. 5 for parabolic or uniform distribution of shaft friction. = 0. 67 for triangular distribution of shaft friction starting from zero friction at pile head to a maximum value at pile point. = 0. 33 for triangular distribution of shaft friction starting from maximum at pile head to zero at the pile point. Ep = modulus of elasticity of the pile (2) settlement of pile point caused by load transmitted at the point. Cp = empirical coefficient depending on soil type and method of construction (see. B = pile diameter qo = ultimate end bearing capacity.
