This course will provide extensive discussions for the design and analysis of retaining systems including gravity walls, cantilever walls, mechanically stabilized earth walls, sheet-pile walls, and diaphragm walls. Students will learn to use computer software to analyze a retaining wall for deep excavations. The course will cover the following topics: lateral earth pressures, retaining wall types, analysis of backfilled walls and in-situ walls, stability of wall and base, settlements due to excavation, strut and anchor systems. Basic concepts of theory of earth pressures behind retaining structures, with special application to design of retaining walls, bulkheads, sheet piles and excavation bracing.
