| Abstract: |
TEMPORARY OR PERMANENT crossings of
existing buried pipelines are often
installed when a new infrastructure is
built. The basic idea behind this study
is to use a geogrid in order to reduce
the stresses on the buried pipeline
caused by the extra loads, such as
construction equipment, extra pipe cover,
vehicular traffic, etc. Although the
existing pipeline has generally not been
specifically designed for these
additional working loads, structural and
serviceability calculations on the
existing pipeline are required in order
to check its integrity and the
suitability of the proposed crossing
method.
An analytical model is proposed and
some numerical analyses are presented in
order to study different geogrid and
trench configurations, and a full-scale
test has been performed with the aim of
checking the theoretical results. The
preliminary results of the study,
performed in Italy by Saipem SpA as part
of the R&D activities of the Onshore
Pipeline Engineering Department, can be
considered of interest to researchers and
engineers working in pipeline engineering
and construction.
