Retaining Wall Diagram
Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance.
Retaining wall diagram. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. Figure 1 example of retaining walls retaining wall structures can be gravity type structures semi gravity type structures cantilever type structures and counterfort type structures.

Earth pressure function of wall displacement.
Lateral earth pressure acting on retaining wall. Soil bearing and stability 8. Soil mechanics simplified 4. Forces on retaining walls 6.
The main purpose of retaining wall construction is to retain soil. Lateral earth pressure coefficients are also performed using this app. Earthquake seismic design 7. Retaining wall design could include any or all of loads and forces which are explained in the following sections.
Building codes and retaining walls 5. Instance a retaining wall can be used to retain fill along a slope or it can be used to support a cut into a slope as illustrated in figure 1. Use this app for reinforced concrete retaining wall design to construct build draw earth pressure distribution diagrams for a layered soil. Closed type abutments axe used where the spilling of the earth in front of the abutments is to be prevented by retaining the earth and therefore such sort of abutments functions as retaining walls in addition to acting as load bearing walls.
That is why soil lateral earth pressure is a major concern in the design. A basement wall is thus one kind of retaining wall. The app is based on active earth pressure formula passive earth pressure formula by the rankine s theory coulomb s theory and caquot kerisel s formula. A wall for holding in place a mass of earth or the like as at the edge of a terrace or excavation.
