Prerequisites
Though there are not official requirements to take this class is highly convenient that the student has in mind the classical mechanics from Physics, stress and deformation concepts from Structural Geology, and water flow from Hidrogeology, classes.
Objectives and Contextualisation
The general objective is to give students the theoretical-practical knowledge of soil mechanics and geological engineering. Special emphasis will be given on applied geological research to solve various geotechnical problems.
Specific objectives aim for students to acquire skills on:
The use of geotechnical characterization techniques, both "in-situ" and in the laboratory.
The integration of various geological disciplines for a multidisciplinary and synthesis work, focused on solving geotechnical problems.
The organization and planning of tasks as well as the development of interpersonal skills that allow team-working.
Expose their team-work activities in class.
Present oral and written exams.
Competences
- Geology
- Display knowledge of the applications and limitations of geophysical methods for learning about the Earth.
- Draw up and interpret geological maps and other means of depicting geological information (columns, correlation frames, geological cross-sections, etc.)
- Identify and characterise minerals and rocks through instrumental techniques, determine their formation environments and know their industrial applications.
- Learn and apply the knowledge acquired, and use it to solve problems.
- Plan the exploration and sustainable development of geological resources.
- Process, interpret and present field data using qualitative and quantitative techniques, and suitable computer programmes.
- Recognise theories, paradigms, concepts and principles in the field of geology and use them in different areas of application, whether scientific or technical.

Lectures
The theoretical part will be taught through lectures. Along with the selected bibliography, the students will have diversified material for complementing the classes that will be available in the virtual classroom and at the library. The theoretical knowledge acquired by the students will be evaluated with written tests.
Laboratory practices / Constructive projects
We will work with a series of data acquired in the laboratory to process, visualize and analyze it at the laboratory class. There are supporting videos that explain the performing of the most significant lab tests to characterize the properties of the soils. Students will be provided with a series of exercises on a real exploration case to learn how geotechnical information is organized, processed, analyzed and synthesized it. Real laboratory and field data will be used to build a geotechnical model on which foundations will be proposed (Laboratory Practical Project)
Field trip
The field trip will take place in the Vallès, Barcelonés area to geotechnical laboratories or construction projects where the student will obtain information on conducting field or laboratory tests.
At the end of the semester, 15 minutes will be allocated for the students to answer the teacher evaluation surveys
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
Assessment
Continous Assessment Activities
| Title | Weighting | Hours | ECTS | Learning Outcomes |

1.Continous Evaluation
S’avaluaren:
- Exercises (30%)
- Two partial exams: 1st partial exam (20%) i 2nd Partial exam (20%)
- Reports from practical work at lab (by teams) (15%)
- Practical Laboratory Project (15%)
- Mandatory assistance to the field trip. We might visit a geotechnical private laboratory or a construction site.
2. Re-evaluation:
- Only exams will be re-evaluated.
- Students must have delivered 2/3 of exercises and the Practical Laboratory Project to have the right to be re-evaluated.
- Re-evaluation can be partial or total, this is: present only one part to be re-evaluated, first or second part of the course, or both parts.
- The best obtained grade obtained in re-evaluation test will substitute in the exams grades to re-evaluate the final grade.
3. Unique evaluation.
- The student who choose this single evaluation option during has to communicate it to the lecturer professor during the first two weeks after the beginning of classes. He/She has to formalize it with Academic Management Area of the Faculty of Sciences infilling a form to ask for this modality.
- The single evaluation will take place the date of the second partial exam and it will consist on:
a) Theory exam(30%)
b) Practical exam (30%)
c) A geotechnical investigation project (40%) that will be defined with the professors at the beggining of the course.
- The student with single evaluation can be re-evaluated only in the exams part as in continous evaluation.
