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…


Lateral Earth Pressure Theory

There are two classical earth pressure theories. They are 1. Coulomb’s earth pressure theory. 2. Rankine’s earth pressure theory. The first rigorous analysis of the problem of lateral earth pressure was published by Coulomb in (1776). Rankine (1857) proposed a different approach to the problem. These theories propose to estimate the magnitudes of two pressures  Full Article…
