Mechanics of Active Earth Pressure Under Surcharge and Seismic Loading Conditions
Computing, Health and Science
Estimation of active earth pressure is generally required for the design of retaining structures, which are commonly constructed in several civil engineering projects. The analysis for active earth pressure involves basic principles of mechanics. In most field situations, surcharge and seismic loadings make the active earth pressure analysis more complex by increasing the number of parameters governing the pressure on the retaining structures. This paper presents a review of the analytical works available on the active earth pressure from both cohesionless and cohesive soil backfills, in order to investigate the mechanics of active earth pressure under field conditions. Additionally, a parametric study is presented to recognise the effect of surcharge and seismic loadings on the active earth pressure. The results obtained are discussed in detail. The graphical presentations made are recommended for use in field applications as design charts.
