The aim of the Course is to provide the theoretical and practical elements on the main types of in-situ geotechnical tests to determine the stratigraphy and the physical and mechanical properties of soil and rock superficial strata.
They represent the more important soil portion in order to engineering geological application and their knowledge is necessary to civil engineering design projects (e.g.: foundations, retaining walls, roads construction, reservoirs), slope stability assessment, natural and artificial slopes stabilization, quarries mining and recovery.
In addition, the elements necessary to acquire, process and interpreting field data and in situ testing to characterize and classify rock masses will be provided.
In situ testing and investigation goals, benefits and limits. In situ testing survey design. Drilling as methodology to subsoil stratigraphic investigation and sampling. Samples quality. Geotechnical in situ tests: Density Test; Field Vane Test (FV); Dynamic Probing (DP), Cone (CPT) and Piezocone (CPTu) Penetration Testing; Standard Penetration Testing (SPT); Plate Load Testing (PLT). Slope movements and deformations monitoring methods: inclinometers, strain gauge, fessurimeters.
Geomechanical survey of rock masses. Rock mass property and behavior. Characterization and shear strength assessment of discontinuities. Rock slope stability assessment: kinematic feasibility analysis and identification of modes of failure. Rock mass classification (Rock Mass Rating and Slope Mass Rating, Q-system) for engineering design and stability analysis.
