Resumen:
Expansive soils can be categorized as one of the geohazards observed in
the urban environment, representing a silent hazard to buildings and
infrastructure. To evaluate this problematic soil it is necessary to
know some of its geotechnical properties. Generally, the average values
of soil properties are used in the methods which characterize the
geological formation and the lithological group, which causes a great
degree of uncertainty. To overcome this problem, this study proposes a
procedure for estimating and modelling the principle soil properties
that have an impact on expansive soils. The selected case study is
located in the Hermanos Cruz neighbourhood in the city of Pinar del Rio
in Cuba. The investigation was organized into the following stages:
primary assessment of the potential expansiveness of the soils,
modelling of the soil properties utilizing 3D geostatistical methods and
finally the cartographic representation of the potential expansiveness
of soils on a Geographic Information System (GIS) platform at different
depth zones which are of importance in the construction of shallow
foundations of engineering works. The application of this methodology in
the Hermanos Cruz neighbourhood revealed that its soils possess a
potential expansiveness of low to medium, apart from some isolated zones
which show a potential expansiveness of medium to high.
