COURSE OBJECTIVES
The course provides the theoretical and objective knowledge related to the identification and determination of the physical and mechanical behavior of geological formations, in the context of the design and study - construction of technical works.

COURSE CONTENT

• Territorial formations (soils): genesis, composition – structure, physical properties, classification properties (gradation, cohesion, activity), swelling, description – classification, mechanical behavior (shear strength – fracture criteria, deformability – solidification).
• Rock material (rocks): composition – structure, classification, physical parameters, mechanical strength, fracture criteria, deformability, intact rock classification
  Rock formation discontinuities: mechanical description parameters (orientation, spacing, spread, wall strength, roughness, aperture), measurements from sample boreholes.
• Sampling drilling for geotechnical investigations: purpose of execution, depth of drilling - arrangement, diameter of sample, drilling equipment - drill bits, methods of sampling soil and rock formations, packaging - storage, examination and description of samples, coring indicators and RQD, compilation of geotechnical borehole sections.
• Geotechnical field tests: Standard Penetration Test (SPT), Static Penetration Test (CPT), Pressure Measurement Test (MPM), Crosshole Test, Permeability – Intrusion Tests (Maag, Lefranc, Lugeon)
• Laboratory and field exercises in: (a) laboratory tests of soil formations (Soil Mechanics) according to standard ASTM, BS and E105-86, (b) on-site geotechnical tests according to standard ASTM and E106-86
