Advanced Soil Mechanics 1

Syllabus

This class deals with shear strength, deformation characteristics and consolidation theory. The shearing behaviors of both cohesive soils and cohesionless soils are discussed with their drainage condition dependency.  The theories for settlement estimation in elastic, consolidation and creep are given with their relevant aspects.  The theories of pore water pressure development by external loading and its dissipation (consolidation) in low pervious cohesive soils are also presented. In this class, recent advances in soil mechanics are provided, together with emphasis on rigorous and reasonable application of soil mechanics to practical problems.
