Geoengineering

The strong worldwide transition towards evolutionary design codes based on reliability concepts attests to the growing awareness of the role and relevance of the considerable uncertainties which are present in the engineering modeling of soil-structure systems. Georisk Engineering is a leading actor in the development and application of statistical, probabilistic, reliability-based and performance-based geoengineering methods and approaches aimed at cost-performance optimization.

Every soil-structure system is unique, both in its physical configuration and in the data and knowledge which are available to model it for engineering purposes. Among engineering disciplines, geoengineering stands out for the high degree of uncertainty which stems from the natural variability of geomaterials, the limited data which are available to characterize it and the inherent imperfection and approximation in the models used in characterization and design. A rigorous treatment of uncertainties allows an enhanced and more realistic qualitative and quantitative comprehension of the behavior of a soil-structure system, both at ultimate and serviceability limit states, as well as a more objective quantitative assessment of the performance level of a system with respect to these limit states. Reliability-based and performance-based approaches are thus significantly beneficial with respect to cost-performance optimization.

Georisk Engineering provides geoengineering services in:

  • Geotechnical analysis and design
  • Earthquake geotechnical engineering
  • Engineering geology

Geotechnical characterization and design can be conducted using statistical and probabilistic methods, for direct implementation in advanced site characterization, reliability-based and performance-based design approaches. Georisk Engineering's specialist expertise includes the application of soft-computing and artificial intelligence techniques, which provide effective solutions to the modeling of complex geotechnical systems.
