Objectives

The DPR June 5, 2001, n. 328 provides that geotechnics, and then the design of geotechnical systems, also falls within the competence of the professional geologist. For the student of the Laurea Magistrale the geotechnical study implies the need and ability to use knowledge, policies and methods of geological sciences: (petrogenesis, geodynamics and structure geological structure; surface and underground water movement, dynamic morphological alteration processes transport, sedimentation, diagenesis, geological survey and underground exploration, engineering geology and geophysical) and integrate them with some essential principles of the physics of construction, design, building site technology.
In this' perspective, the course uses the process of analysis and verification of the main geotechnical systems to stimulate and train the student to use, integrate and improve, their knowledge of basic geology and applied for the proper construction of the geological model and the geotechnical model that are a prerequisite for geotechnical calculations provided by law.

The illustration of practical examples of calculations for the limit state and basic knowledge of the physics of construction, aims to outline the role and limits of responsibility of the geologist in the multidisciplinary field of geotechnical engineering tools to provide some cultural to allow the necessary comparisons between knowing interdisciplinary geological and engineering technician.

- using the results of the survey for the construction of the geotechnical model
- geotechnical calculations with the criteria laid NTC/2008

Verification of learning

The course is divided into 5 chapters of varying duration. At the conclusion of each chapter, a written verification of the degree of learning consisting of multiple choice questionnaire and / or free.

The topics of Chapter 5, will be verified through peer review of geotechnical calculations with the methods prescribed by the NTC 2008.
