1 1 Retaining Wall
2 Retaining Walls What are retaining walls Retaining walls are soil-structure systems intended to support earth backfills. Type of retaining walls Gravity retaining wall gravity walls rely on their own weight to provide static equilibrium. typically made of plain (unreinforced) concrete or stone blocks. Cantilever retaining walls cantilever walls derive a portion of their stabilizing forces and moments from the backfill soil above the heel. require the use of steel reinforcement to resist the large moments and shear stresses.

5 Retaining Walls 5 MSE walls Mechanically Stabilized Earth (MSE) walls derive their stability from the internal stresses developing at the interface between the soil and the reinforcement elements. MSE walls are constructed by compacting the soil in layers separated by reinforcement strips or sheets. Reinforcement strips are attached to facing units, and extend far enough into the backfill to ensure adequate pullout resistance. Soil-Nailed walls

9 Cantilever Retaining Walls Basic Principles Cantilever walls are made of reinforced concrete, & come in different geometries. Rely on their self-weight to resist sliding & overturning, but derive part of their stability from the weight of the backfill above the heel of the wall. 9

14 Cantilever Retaining Walls Basic Design Principles In addition to the external stability, cantilever walls must also satisfy internal structural. The wall section should be able to withstand the shear stresses and bending moments resulting from the lateral earth pressure as well as the difference in pressure between the top and bottom faces of the base. 14
15 Cantilever Retaining Walls 15 External stability In analyzing or designing for external stability, all the forces acting on the structure are considered. These forces include lateral earth pressures, the self-weight of the structure, & the reaction from the foundation soil. The stability of the wall is then evaluated by considering the relevant forces for each potential failure mechanism. The wall has to be stable against: Sliding Overturning Bearing capacity FS BC q q all max 1
