Retaining Wall Design With Sloped Backfill

Soil mechanics simplified 4.
Retaining wall design with sloped backfill. Surcharge loads acting on retaining wall. Infor mation bulletin 221 describes retaining walls with level backfill. A gravity retaining wall shown in fig 3 is the one in which the earth pressure exerted by the backfill is resisted by the deadweight of the wall which is either made of masonry or of mass concrete the stress develops in the wall is very low these walls are no proportioned that no tension is developed anywhere and the resultant of forces remain within the middle third of the base. Forces acting on a retaining wall.
It can be either dead loads for example sloping backfill above the wall height or live load which could result from the highway or parking lot paving or adjacent footing. Ments for retaining walls with sloping backfill. Information bulletin wall height is measured from the top of the footing to the top of the wall. Forces on retaining walls 6.
These bulletins are intended to provide a simple alternative to designing minor retaining walls but should be used only where appropriate soil condi tion at the site. Design and analysis of retaining walls 7 a level backfill without surcharge. The walls shown here are designed to retain only sloping backfill. Design procedure overview 3.
Building codes and retaining walls 5. Figure 1 example of retaining walls. D sloped backfill with surcharge fig 8 4. Retaining walls are structures that support backfill and allow for a change of grade.
No special inspection is required for retain walls not shown in tables a and b on page 3 must be designed specifically for the existing conditions. Lateral forces on retaining wallsence 454 assakkaf sloping backfill if a sloping backfill is considered then the assumed active pressure distribution is shown in figure 4 where hs kpwehb2 and hb is the height of the backfill at the back of the footing and ka is the coefficient of active earth pressure. Along with sloped landscapes where water runoff causes hillside erosion ideal locations for a retaining wall system include spots downhill from soil fault lines and where the downhill side of a foundation is losing supporting soil or its uphill side is under pressure from sliding soil. Thus 6.
Foundation engineering chapter 8. Soil bearing and stability 8. No building foundation retaining. Retaining wall design 10 editionth a design guide for earth retaining structures contents at a glance.
Surcharge loads acting on retaining walls are additional vertical loads that used to the backfill soil above the top of the wall.
