CIVL20221 Geotechnics 2 10 Semester 1 Undergraduate Level 2 Majid Sedighi Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 <p>This is an introductory course to Soil Mechanics that covers the following fundamental concepts:</p><p>1)&nbsp;&nbsp; Strength of soils: Definition of strength in particulate multi-phase materials under different stress paths (drained and undrained conditions). Derivation of strength parameters from laboratory tests, including: triaxial, direct and simple shear tests. Introduction to main constitutive models used for saturated and dry soils, including the Mohr-Coulomb yield criterion and more advanced constitutive models based on the critical state soil mechanics.</p><p>2)&nbsp;&nbsp; Compressibility of soils: Introduction to Terzaghi&rsquo;s theory of one-dimensional consolidation. Derivation of compressibility and stiffness parameters from conventional laboratory test (oedometer test). Definition of degree of consolidation. Application of the theory of consolidation for evaluation of consolidation settlement in clay.</p><p>3)&nbsp;&nbsp; Stability of earthworks: Classification of landslides. Use of limit equilibrium method to determine stability of slopes, embankments and excavations. Introduction to methods of analysis used in routine practice, outlining their assumptions and limitations.</p><p>4)&nbsp;Introduction to Critical State Soil Mechanics: Introduction to critical state framework to link compressibility, stress path and strength of soils.</p> <p>Soil mechanics may be defined as the study of the engineering behaviour of soils, with reference to the design of civil engineering structures made from or in the art. Examples of these structures include embankments, cuttings, dams, earth retaining walls, tunnels, sub-surface waste repositories and the foundations of buildings and bridges.&nbsp;&nbsp;</p> <p>To introduce the fundamental concepts of soil mechanics and demonstrate through the use of case histories and laboratory activities how geotechnical aspects influence design, construction and maintenance of engineering structures, with emphasis on earthworks (slopes, embankments, excavations)</p> <p>1) Strength of soils: Definition of strength in particulate multi-phase materials under different stress paths (drained and undrained conditions).
