GENERALIZED COULOMB ACTIVE-EARTH PRESSURE FOR DISTANCED SURCHARGE. TECHNICAL NOTE

In this note, the author reviews the advantages of the Coulomb method for determining active-earth pressure for distanced surcharge. The note reveals that various closed-form solutions are applied in geotechnical engineering problems; however, most earth-pressure-active coefficients are derived from soil weight alone and do not take surcharge applied on the ground profile into account. The Coulomb approach is based on the limit-equilibrium method and is reliable for the case of the active state. Also, the Coulomb method allows solving earth- pressure problems with various boundary conditions, which for the purpose of this note, is more appropriate. Two examples of earth-pressure problems are presented. The analytical solution is compared to the Coulomb graphical approach, assuming various slopes, surcharge, and earthquake loadings. The author concludes that a closed-form solution is strictly dependent on boundary conditions, that is, one must verify the compatibility of the solution with the boundary conditions of each problem.
