Into what two categories can earth retention systems be broken down? - Answer: 1. Externally stabilized systems (resistance from the self weight and stiffness of the wall)
- Internally stabilized systems (resistance from the soil itself)
Examples of externally stabilized systems - Answer: -gravity retaining walls
-cantilever retaining walls -counterfort retaining walls -sheet pile walls -soldier pile walls -crib walls
Examples of internally stabilized systems - Answer: -reinforced soils
Typical geotechnical design of retaining wall involves... - Answer: 1. Selection of initial trial section -length of heel/toe (base slab) -thickness of the stem and base slab
- Calculation of forces acting on the wall
