  • To cover the design and analysis of a variety of different earth retaining structures.
  • In particular the course aims to cover the following: Types of retaining structure. Design requirements. Rankine states of stress. Coulombs method. Approximate methods using curved failure surfaces. Mobilisation of earth pressures. Layered soils. Water pressures. Tension cracks. Earth pressures due to surcharges. Earth pressures due to compaction. Design of gravity retaining walls. Design of embedded cantilever walls. Design of propped/anchored embedded cantilever walls. Effect of prop position. Effect of wall stiffness. Multi propped/anchored walls. The critical height of a vertical cut. The critical depth of excavation. Prop loads and bending moments, Numerical methods.
