Geotech Week 10 Workshop

Designing for AS4678 refers to which method

• Global factor of safety

• Partial factor of safety

• Coulomb's Theory

What's the main difference between gravity wall design and embedded wall design?

Tick ALL correct options

• In embedded wall design, don't account of self-weight

• In gravity wall design, gravity is taken as 9.81 rather than 9.8

• In gravity wall design, the point of rotation is at the toe of the retaining wall

• In gravity wall design, sliding failure is a function of friction against the base of the footing

What would the load factors be?

• 1 - Dead load of wall and contained soil
  2 - Dead load of earth pressure behind wall
  3- Dead load on fill in front of wall
