Works

made with OUM

Geosolving has developed numerical analyses to evaluate the effect of the construction of the works planned for the new Pavilion 0 of the Giannina Gaslini institute in Genoa on the Lamba Doria double-track railway tunnel of the Genoa-Pisa line. The numerical analyses were developed both with a two-dimensional finite element model (FEM) using the RS2 software, and with a three-dimensional finite difference model (FDM) with the FLAC3D software. The analyses, conducted on the basis of the geometrical, geological and geotechnical information available, made it possible to reproduce the stress-state conditions of the subsoil around the tunnel in the actual state and following the construction of the buildings, highlighting the induced stresses and strains on the tunnel by the new construction and the existing buildings.

Geosolving was in charge for the analysis of the gravitational phenomenon of the eastern slope of Mount Saresano. The aim was to update the DVR (Risk Assessment Valuation) of the factory located at the foot of the slope affected by the stability problems. The instability initiation phase was studied through the use of advanced numerical models with hydraulic, seismic, gravity, and rheological forcing for studying the different instability scenarios. They were used to identify velocities that can anticipate the development of instability phenomena. From the results of the numerical modeling and the interpretation of the monitoring data, pre-alert, alert, and alarm thresholds were then defined aiming at the safe management of the factory’s activities.

Discrete element numerical modelling (DEM) under two-dimensional conditions are adopted to assess how waste FIBC are deposited. An innovative and useful methodology to support the planning and management process of a landfill. The activity included the following stages.Determination of the properties to be assigned to the numerical model by simulation of the mechanical behaviour of the bag’s filling material by simulating real in situ loading tests.Numerical simulation of the behaviour of individual bags and of groups of bags laid on a horizontal plane according to a procedure that reproduces the methods adopted in landfills.Numerical simulation of design configurations to reproduce the stacking of bags according to the geometries adopted in situ and stability evaluation.
The modelling has provided operative inputs for the optimization of the disposition modalities for the big bags in the landfill.
