Obiettivi Formativi
By the end of the course, the student must be able:
- to recognize type and occurrence of natural and man-made slope movements (Dublin descriptor D1. Knowledge and understanding)
- to assess/evaluate the key geotechnical parameters that govern slope stability (D3. Making judgements)
- to use methods for slope stability assessment, modelling of slope movement and back-analysis of failed slopes (D2. Applying knowledge and understanding)
- to judge capabilities and limitations of slope stability analysis software (D3. Making judgements)
- to decide the fundamental steps for landslide investigations and select remedial measures (D2. Applying knowledge and understanding)
- to use the appropriate terminology of the discipline (D4. Communication skills)
- to apply knowledge to practical problems (D2. Applying knowledge and understanding; D5. Learning skills).
Prerequisiti
Soil mechanics, fluid mechanics, soil dynamics
Metodi Didattici
Ex cathedra, exercises, case study analysis.
This course is part of an experimental program carried out by University of Florence on "blended learning". Therefore, the course syllabus will be delivered both "on-site" in a traditional way (4 CFU) and "off-site“ in an asynchronous way (2 CFU) for a total of 6 CFU (48 hours)..
“On-site” hours will take place in Santa Marta building (Room 029 on Monday and room 047 on Tuesday) through lectures, software demonstrations, seminars, quizzes and group projects.
“Off-site” hours will take place virtually within the weekly timetable but they will not request any presence of the students or the lecturer on site or any meeting on line. During "off-site" hours the students will study the material made available by the lecturer (“flipped classroom”) on the topic considered (presentations, chapter of books or recordings) and after, they will fill a questionnaire or they will participate to a forum on the same topic before the “on-site” hours (“asynchronous way”). Any further discussion and group project on the same topic will take place during the next "on-site" hours.
One week before, every week, the lecturer will announce when "on-site" hours will take place.
Altre Informazioni
office hours: monday 11-13: on site (room 126, 1st floor, S. Marta) or on line (https://unifirenze.webex.com/meet/jfacciorusso)*
*an e-mail of request from the student as well as the confirmation by the lecturer are needed in both cases
Modalità di verifica apprendimento
Two intermediate tests, project (including technical report and discussion) and oral (optional if the average of the votes is greater than 18) are needed to verify if the student is able:
