tress measurements and stress monitoring
applied to geostructures
tresses are a prominent parameter
when assessing stability of geostructures
over their life cycle. In situ stress
measurements are then important to early
Pre-existing stress field
detect high stress zones and ground issues as
well as to set up numerical geomodels to
Stress gradients
enhance the prediction of stress fields and
potential failure mechanisms .
Quasi static stress changes
NERIS offers stress measurement
Dynamic stresses
solutions and services to investigate control
in situ quasi-static and dynamic stress fields
Cyclic Shear Ratio
exerting in the rocks or soils in order to
provide a deeper insight into risk assessment
NERIS has completed numerous stress
Field applications
measurement projects in a wide range of
situations, adapting methods and tools on

operating conditions on site. INERIS identifies
and sizes the most adapted stress monitoring
solution in order to collect high quality data
and to optimize the analysis and expertise for
better decision making.
