Concept of Retaining Walls Design -Calculation of Earth

A retaining wall which retains earth level upto the top of the retaining wall is a wall without surcharge. If the earth on the earth retained side is not level or the earth carries loads, the earth is said to have surcharge.

Traffic live load surcharges on retaining walls - Earth

The further the surcharge is from the wall, the less load is applied to the wall. Generally if you can keep the edge of road at least 5 feet from the face of the wall, the pressure will be managable. To analyize the pressure fast and dirty: assme a 250 psf strip surcharge at edge of road to edge of road.

surcharge loading on retaining wall - Structural

In the past, I normally design retaining walls with a surcharge of, between 10 and 20 kN/m2 and applied it directly to the retained structure. I have no problems understanding in applying a factor to soil pressure ie, because it depends on the basic principles of "soil mechanics", angle of friction ..etc. .
