Course Goals / Objectives:
Be able to identify for a specific project the advantages and disadvantages of different numerical techniques, and discuss the advantages and disadvantages of each technique.
Use numerical methods in stage-by-stage analyses for earth structures such as levees and dams, to estimate, seepage, pore pressures, displacements, and factors of safety.
Create numerical models for soil-structure interaction problems and compute solutions including various foundation systems (e.g., footings, driven piles, drilled shafts, and mat foundations)
and retaining wall elements (e.g., soldier piles, tiebacks, soil nails, and anchors).
