Strengthening and Rehabilitation of Foundations

Soil Mechanics and Foundations.

The teaching methodology is mainly based on theoretical-practical classes, in which the presentation of the main concepts, methods and techniques is complemented by the analysis and discussion of practical examples and real cases related to foundation rehabilitation and strengthening.

Active student participation is encouraged through the discussion of engineering solutions, analysis of pathologies, interpretation of real situations and critical debate on different intervention techniques.

Independent study and research are promoted through the development of an applied assignment involving literature research and technical analysis, with the main results being presented and discussed orally.

National and international case studies are used to consolidate the acquired knowledge and bring students closer to the methodologies and solutions adopted in professional practice.

By the end of the course, students are expected to be able to:

• Identify the main pathologies associated with shallow and deep foundations, particularly through visual inspection of their effects on structures;

• Identify and understand the main causes of foundation pathologies;

• Distinguish soil improvement and soil reinforcement techniques as possible solutions for foundation strengthening;

• Understand the main construction processes available for foundation rehabilitation and strengthening interventions, being able to adapt previously acquired design methodologies and apply new solutions introduced in the course;

• Understand the advantages, limitations and fields of application of the main foundation strengthening techniques covered in the course.

4. Foundation pathologies and diagnosis:

• Analysis of foundation pathologies;
• Analysis stages and diagnostic methodology;
• Symptomatology;
• Problems associated with old foundations;
• Integrated structural and foundation diagnosis;
• Visual and instrumental inspection;
• Monitoring of deformations, cracking and vibrations.

5. Application and discussion:

• Presentation and discussion of assignments;
• Questions, clarification and critical debate;
• Case studies of national and international projects involving successful foundation rehabilitation and strengthening solutions.

The assessment of the course comprises two components:

• Development assignment, to be presented at the end of the semester: 10 points;

• Final exam: 10 points.

The final grade is determined as follows:

Final grade = Assignment + Exam
