Objectives
The course aims to provide students with the main theories and applications useful to understand the behaviour of the structures retaining excavations and embankments and their engineering modelling related to various stress conditions.
Prerequisites
Preliminary knowledge to the course is: stress and strain conditions of monophasic means; field equations for the simulation of the mechanical behaviour of loose rocks; geotechnical characterization of soils.
Contents
Earth pressures
Limit equilibrium states of a half-space of incoherent soils with or without water; cohesive soils; effect of apparent cohesion; limit equilibrium conditions of an embankment behind a stiff and rough wall of finite height; curvature of the surface of rupture; calculation of the limit equilibrium processes driven by flat and non-flat global failure surfaces; effects of horizontal displacements on the forces generated by an embankment.
Retaining walls
Laws and regulations; phases of the project, calculation of earth/water pressures, irregular surfaces of the embankment, thrust due to overload; influence of pore pressures, measures for the control of the water system; thrust induced by cohesive soils; Cantilever walls and buttresses; semi-empirical methods for the calculation of the thrusts; stability of retaining walls; dynamic loads on supporting walls.
Sheet walls
Laws and regulations; type; metal sheet piling, reinforced concrete sheet walls both prefabricated and cast in situ; stability of trenches dug in mud. Design criteria and calculation of the thrusts acting on a cantilever sheet wall: in loose soils, in the absence and presence of water; in clay soils. Anchored sheet walls: calculation procedures and comparisons; multiple anchored sheet walls.
Anchors
Laws and regulations; plates and beams as anchor; injected bulb anchors; anchor design, global stability.
Reinforced excavations
Laws and regulations; instability of the bottom of the excavation, displacements associated with excavation operations.
Reinforced soil
Reinforced soil walls. Elements of design and check of internal and external stability.
Teaching Methods
The course covers lectures and classroom exercises. Technical visits to sites of interest are also scheduled.
Verification of learning
The achievement of the fixed objectives will be assessed through an oral examination concerning the topics covered in class and the presentation of a case study analysed by each student within a group work.
