Subsurface geological-geotechnical modelling to sustain underground civil planning

Quantitative assessment of engineering geological suitability for multilayer Urban Underground Space

“…Fremming (2007) method for modeling geological structures includes identifying fault planes in a geologic structure, and creating a set of substantially vertically oriented pillars along the fault plane. De Rienzo et al (2008) pointed out the 3D GIS model could manage the planning and construction of future underground works. Jones et al (2009) proposed the 3D visualization of multi-scale geological models, which can be another way to realize the UUS detail management.…”

Analyses of the Distribution and Nature of the Natural Cementation of Quaternary Sediments: The Case of the Turin Subsoil (Italy)

“…The comparison have shown different geotechnical parameters according with the cementation variability founded in the boreholes description, that has allowed to assign different geotechnical parameters to each cementation class as follows: C1 class-Elastic module 150 MPa, friction angle 36°, coesion 0.01 MPa; C2 class-Elastic module 190 MPa, friction angle 38°, coesion 0.03 MPa; C3 class-Elastic module 230 MPa, friction angle 40°, coesion 0.1 MPa (de Rienzo et al 2008).…”

“…A tri-dimensional model, which shows the spatial distribution of the cementation for the whole investigated area, has therefore been set up (de Rienzo et al 2008(de Rienzo et al , 2009. The identification of the cemented horizons, and the definition of their spatial continuity and degree of cementation, is of particular importance in the choice of the technology that can be used for the excavation and for the support of the created voids.…”

Geotechnical evaluation of the alluvial soils for urban land management zonation in Gharbiya governorate, Egypt

“…This can play a decisive role to help efficiently prioritize management zones with cost effective optimization of the construction times, efficient setting of mitigation measures, and designing projects for safe extension with appropriate and reliable foundation system to compensate for risks or overcosts (e.g. Tilford, 1994;Parsons and Frost, 2002;Hack et al, 2006;De Rienzo et al, 2008). This dictates the use of a multidisciplinary approach that can integrate the multivariate statistical and geostatistical techniques in a Geographical Information Systems (GIS) environment.…”
