Theoretical classes with audiovisual media support.
Practical classes which include speciality reports analysis, core logging, powerpoint presentations by students and field trips.
2 midterm tests (T1, T2) plus a group task (Tg) will be graded and allow to be dismissed from final exam.
The maximum final classification will be calculated as follow:
Final grade: 0,8.(T1+T2)/2 + 0,2.(Tg) = 20 values
Access for the Final Exam will be guaranteed in the case of, at least, 2/3 of attendance of all classes and presentation of the group task.
The frequency of the unit will be valid for the corresponding academic year. In case of failure of the final exam, it will be valid too for the following academic year.
Site investigation. Mechanical exploration methods and in situ tests. Definition, purposes and programing.
Direct methods: trenches, pits, shafts and galleries. Direct and semi direct methods: boreholes, penetration probes and in situ tests; characterization, domain of application and equipments. Presentation of results. Some common correlations. Borehole logging and drilling parameters registration.
Soil and water sampling and sampling methods. Soil samplers. Sample quality, reliability, validity and representativity; their influence in the studies.
Introduction to the most common geotechnical tests performed along the exploration, their main purposes and limitations.
Preparation of reports, price lists and specifications for the site investigation programs.
