Resumo: | |||||||||||||
This work is intended to assemble, in the light of a
qualitative approach, what is already known about the
changes over time in the bearing capacity of piles, setup
and relaxation. The importance of such alterations is
significant. After the installation process, the piles may
keep their initial loading capacity, set it up by
increasing it from a non-predictable percentage (which
may eventually quadruple) or relax, losing most of its
resistance (up to over percent). The cost of such phenomena
justifies per se the need of an improved comprehension of
such processes, and in the present work, a first step of a
broader research project, the results and observations on
the subject were collected and assembled. Representative
cases found in the literature which contemplate variety in
soil behaviour due to the driving of piles were selected
and transcribed. Experimental evaluations where a growth or
reduction in the bearing capacity of driven piles over
time, eg. set-up and relaxation, were given priority. It
was not the concern of this work to restrict the set-up and
relaxation processes to more recent research because the
initial intuitions, though not in charge of the present
technological development, were not so distant from the
proposals and models which followed. We thus deem as
essential to foundation engineering a further insight into
the subject, which will permit better and safer
anticipations of the behaviour of driven piles over time,
in view of the risks and economic losses which may arise
from its absence. It is hoped that the present
dicussion, by contributing to further a qualitative global
view of the matter, may give rise to the adoption of
scientifically ethical practices. To such, it is
recommended that the information on such phenomena be made
public.
