      • Weight of the wall
      • Pressure from retained soil
      • Pressure on foundation of wall
      • Characteristics of soil
      • Loads on retained soil
      • Impacts of water—liquid and frozen
      • Vibration
      • Expansion/contraction
   Equations and examples

Geosynthetics and Retaining Walls, Embankments and Slopes

   Calculations and software
   Types of retaining walls
      • Learn to visually identify geosynthetics as to type, method of manufacture, relative strength, relative permeability, and relative cost

Slope Stabilization Techniques
