Cantilever retaining walls, Rankine's theory, Coulomb's theoryAbstract
Two methods for determining the static actions, due to soil weight, on cantilever retaining walls are presented. One of the methods is based on Rankine’s theory and the other on Coulomb’s theory. The methods are described and compared and the actions determined by them are shown adimensionally. A parametric analysis is performed, studying the influence of the soil-to-wall friction angle, the inclination of supported soil, the height of the wall footing and the unit weight of the wall footing. It can be concluded that the method based on Rankine’s theory can be applied in most cases, because when compared with the one based on Coulomb’s theory the results are either the same or conservative, and is slightly unconservative for the cases where the soil-to-wall friction angle is less than the inclination of the supported soil.
