δ = Friction angle between concrete and soil at the bottom of the retaining wall. S = W × tan(δ) = × tan(20°) = kN per 1 m length of the wall. Weight of the retaining wall is given to be kN per 1 m length. Factor of safety against sliding = / = Step 3: Find the resistance against overturning (O)Overturning will occur around point “X” of the retaining wall. Backfilling with a clay soil instead of sand can increase the load by double or more, while going from an 8-foot to a foot wall, just a 25% height increase, adds 50% to the lateral pressure. Taller walls backfilled with heavier soil risk failure unless correct design methods are followed.

() investigated the pressures exerted by clay backfills against retaining structures and concluded that previously developed theories (e.g. Rankine's, Coulomb's. There are three categories of lateral earth pressure and each depends upon the movement experienced by the vertical wall on which the pressure is acting as shown in Figure 2 (Page 4).

In this course, we will use the word wall to mean the vertical plane on which the earth pressure is acting. The wall could be a basement wall, retaining wall, earth.

During the compaction of the clay the wall was supported as it was considered necessary to protect the load cells from any excessive force that could damage them.

Simons, C.R. The objective of the presented research is to investigate methods used to calculate earth pressures against- and the stability of retaining structures.

The classical methods of calculating earth pressures are covered in detail. They are named after their creators Charles-Augustin de Coulomb and William John Macquorn Rankine.

At Rest Lateral Earth Pressure: The wall may be restrained from moving, for example; basement wall is restrained to move due to slab of the basement and the lateral earth force in this case can be termed as" P m". Active Lateral Earth Pressure: In case of the wall is free from its upper edge (retaining wall), the wall may.

To this end, three centrifuge tests were selected: (1) an earth embankment founded on liquefiable soil (Adalier ;Adalier et al.
