Tag: Lateral earth pressure Lateral Earth Pressure retaining wall problem example 1

A gravity retaining wall is required to be designed for seismic conditions for the active state. The following data are given: Solution From Eq. (11.79) For all practical purposes, the point of application of Pae may be taken as equal to H/2 above the base of the wall or 4 m above the base in this case.

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 the earthquake forces. Murphy (1960)

If the wall is rigid and does not move with the pressure exerted on the wall, the soil behind the wall will be in a state of elastic equilibrium. Consider a prismatic element E in the backfill at depth z shown in Fig. 11.5. Element E is subjected to the following pressures.       The expression for oh at

Tag: Lateral earth pressure Introduction to Lateral earth pressure

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. Some of the purposes for which retaining walls are used are shown in Fig. 11.1. Retaining walls may retain water also. The earth retained may be natural soil or fill.
