Pile Group Settlement

Cohesionless soil

The analysis of a pile group in a cohesionless soil is developed based on the linear theory of settlement (Poulos). The load-settlement curve for a pile group and the value of the total settlement sg is increased by so-called group settlement factor gf.

An immediate settlement of the pile group increased by the group settlement factor is provided by:

where:

sg

-

pile group settlement

gf

-

group settlement factor for a cohesionless soil (according to Pile Buck Inc. 1992)

s0

-

settlement of a single pile (determined, e.g. from the load-settlement curve)

d

-

pile diameter

bx

-

minimum width of pile group

Cohesive soil

The pile group settlement in a cohesive soil is determined as the settlement of a substitute foundation at a depth of 0,67*L, having a width B and a length B'.

Analyses to calculate settlement are described in more detail in "Settlement analysis".
