17 18 Over the last decade, terrestrial laser scanning and digital terrestrial photogrammetry techniques have 19 been increasingly used in the geometrical characterization of rock slopes. These techniques provide 20 innovative remote sensing tools which overcome the frequent problem of rock slope inaccessibility. 21 Comprehensive datasets characterizing the structural geological setting and geo...

This paper presents a concept for the application of particle swarm optimization in geotechnical engineering. For the calculation of deformations in soil or rock, numerical simulations based on continuum methods are widely used. The material behavior is modeled using constitutive relations that require sets of material parameters to be specified. We present an inverse parameter identification t...

To study the coupled thermo-hydrologic-geomechanical processes and their influence on gas and nuclide transport in a two phase flow through the porous medium, a coupling of the thermo-hydrodynamic code TOUGH2 and the thermo-mechanic code FLAC3D is described and applied to analyze three dimensional gas, heat and nuclide transport in a repository for disposal of heat generating nuclear waste in a...

We performed an integrated study of multistage hydraulic fracture stimulation of two parallel horizontal wells in the Bakken Formation in the Williston Basin, North Dakota. There are three distinct parts of this study: development of a geomechanical model for the study area, interpretation of multiarray downhole recordings of microseismic events, and interpretation of hydraulic fracturing data ...

Stability of Geosynthetic Lining Systems is, for a geotechnical standpoint, a complex matter. Three geomechanical questions were identified: sliding of the geosynthetic lining system on slope, pull-out strength of the geosynthetic anchorage at the top of the slope, rain erosion of the cap cover. Research programmes carried out in France on these topics, , are presented. Use of laboratory facili...

The development of engineering activities involving shales such as the extraction of shale gas and shale oil, the nuclear waste geological storage and the sequestration of CO2, has led to an increasing interest toward the geomechanical behaviour of this geomaterial. In the context of such engineering applications, a deep understanding of the hydro-mechanical behaviour of shales is of primary si...
