Resumo: | |||||||||||||
The technique of soil reinforcement by inclusion of
geosynthetics has been
subject to significant development worldwide, with direct
applications in slope
stabilization and earthfills over soft deposits. The use of
geogrids as a soil
reinforcement element is an attractive alternative,
although still with very little
application in Brazil.
This work presents the results of an investigation into
soil- geogrid
interaction by means of pull-out tests. Both field and
laboratory pull-out tests were
carried out in order not only to make clear the pull-out
mechanism but also to
determine the parameters for design and analysis of
reinforced soil structures. The
testing equipments, specimen preparation and testing
procedures are described in
detail.
The field pull-out tests were performed with three
different types of
geogrids in a research area in Jacarepagua, Rio de Janeiro.
Sandy and residual soil
surcharge fills of 0,5 to 2m in height were used. Details
of the anchored reaction
structure are also presented.
The laboratory pull-out tests were performed in the
geotechnical laboratory
at CEDEX, in Spain, with the same types of geogrids and
soils. Details of the
cubical pull-out box (1m in dimensions) are presented.
The influence of the type of geogrid, type of soil,
confining pressure and
tests procedures on the pull-out stiffness and resistance
of the geogrids are
discussed by analysing the results of the experimental
program.
