Abstract
A method of design for short, square pier foundations in
cohesionless soil is presented for the particular case where
lateral load is applied well above ground level, a condition
experienced by catenary mast foundations used in electrified
rail networks for example. The method is based on three-dimensional
non-linear finite element analyses incorporating
the hyperbolic soil model and the moment-carrying capacities
of piers ranging from 0.8-2.4m square and up to 2.4m deep
for rotations under working conditions of 1° and 2° are given.
The results are found to compare well with centrifuge tests on
small model piers and with existing design methods.
