Highways and railways
infrastructures
TERRASOL
works in co-operation with project management teams or contractors
for the study and works supervision of large infrastructures,
including soil treatment, cut slopes, embankments on compressible
soils and civil works foundations.
Bridges, structures,
buildings and industrial installations
Foundation
projects for major structures, sometimes of exceptional dimensions,
which need stability analyses (ULS computation) and deformation
analyses (SLS computation). TERRASOL can contribute its
understanding of the ever-present soil-structure interaction
nechanisms and offer optimised solutions, for example with
reinforcement by rigid inclusions. Dynamics analyses and
liquefaction studies are at times included.

Underground structures
Tunnel projects comprise many
factors - of which geology is key - and cannot be designed without a
sound grasp of execution methods, soil-structure interaction
mechanisms and evaluation of the induced deformations, notably for
projects in soils and soft rocks and in an urban environment. In this
context, TERRASOL offers its global project philosophy in a
multi-disciplinary approach. It is also an area that often calls for
more recent techniques (for example, soil treatment and
reinforcement) and therefore for novel approaches such as stability
and deformations of the tunnel face - a
TERRASOL speciality.

Major earthworks
A key domain
for major projects in soft soil areas or on unstable
slopes. TERRASOL offers its competency in slope stability
analysis methods and settlement analysis. Special techniques for
improving or reinforcing the soils can often lead to original and
economic solutions.
Large excavations
Underground
infrastructures combining retaining structures techniques, sometimes
playing a supporting role, and soil-structure interaction mechanisms,
where TERRASOL has developed specific know-how. In
addition, soil reinforcement techniques are often needed, not to
mention the hydrogeological aspects.

Maritime and waterways
structures
These
projects more often than not combine retaining structures, shallow or
deep foundations and earthworks, generally on difficult
ground. TERRASOL is able to analyse the complex
soil-structure interaction mechanisms as well as water seepage, one
of the fundamental aspects of these structures.
