Structures that are built to retain vertical or nearly vertical earth banks or any other material are called retaining walls. Retaining walls may be constructed of masonry or sheet piles.
In all these cases, the backfill tries to move the wall from its position. The movement of the wall is partly resisted by the wall itself and partly by soil in front of the wall.
Sheet pile walls are more flexible than the other types. The earth pressure on these walls is dealt with in Chapter 20. There is another type of wall that is gaining popularity. This is mechanically stabilized reinforced earth retaining walls (MSE) which will be dealt with later on.
This chapter deals with lateral earth pressures only.

Lateral Earth Pressure on Retaining Walls During Earthquakes

Ground motions during an earthquake tend to increase the earth pressure above the static earth pressure. Retaining walls with horizontal backfills designed with a factor of safety of 1.5 for static loading are expected to withstand horizontal accelerations up to 0.2g. For larger accelerations, and for walls with sloping backfill, additional allowances should be made for  Full Article…

Passive Earth Pressure problem example 2

For the data given in Example 11.15, determine the reduction in passive earth pressure for a curved surface of failure if 8 = 30°. Solution For a plane surface of failure P from Eq. (11.76) is It is clear from the above calculations, that the soil resistance under a passive state gives highly erroneous values for  Full Article…

Passive Earth Pressure problem example 1

A gravity retaining wall is 10 ft high with sand backfill. The backface of the wall is vertical. Given 8= 20°, and 0 = 40°, determine the total passive thrust using Eq. (11.76) and Fig. 11.24 for a plane failure. What is the passive thrust for a curved surface of failure? Assume y= 18.5 kN/m3. SOLUTION
