Calculation of Pile Base Settlement

The magnitude of pile head settlement w1,d is determined as follows:

where:

wbase,d

-

pile base settlement due to acting force

wbase,d,1

-

pile base settlement due to force acting at the base

wbase,d,2

-

pile base settlement due to force acting on the shaft

wel,d

-

pile settlement due to elastic compression

The magnitudes of settlements wbase,.d,1 and wbase,d21 are determined from built-in graphs according to the NEN6743 standard. The value wel,d is given by:

where:

L

-

pile length

Fmean,d

-

mean of force acting on the pile

Aplast

-

pile shank cross-sectional area

Ep,mat,d

-

modulus of elasticity of the pile material
