Cycles of Study/Courses
Teaching language
Portuguese
Objectives
Explanation of the concepts associated with lateral earth pressure. Static and dynamic design of gravity retaining walls. Introduction to soil reinforcement. Design of reinforced earth walls.
Program
Lateral earth pressure; active and at rest earth pressure; displacements and pressures. General aspects of earth retaining structures; classification. External design, ultimate and service limit states. Seismic analysis of gravity walls; pseudo-static methods, displacement methods, analytical methods based on elastic solutions, numerical and experimental methods. Massive structures: masonry, concrete and gabions. Reinforced concrete walls: L shaped, with counterforts and variations.
Introduction to reinforced soils. Classification of earth retaining structures based on soil reinforcement. Soil-reinforcement interaction; friction-adhesion; passive earth pressure.
Structures composed by soils reinforced with metallic elements (strips and meshes) and with geosynthetics (polymeric strips, geogrids, geotextiles and textile thread).
