Abstract

The earth pressure with finite width is often encountered in engineering. Theoretical research and engineering practice show that the classical Rankine and Coulomb equations are not suitable for active earth pressure with finite width. In this paper, based on the lower bound theorem in plastic mechanics, the lower bound model for the active earth pressure of cohesionless soil with finite width is created, and the corresponding numerical solution method is provided. The active earth pressures and the distributions under different soil heights are calculated and analyzed. The results indicate that the active earth pressure of cohesionless soil with finite width is smaller than the corresponding Coulomb active earth pressure. As the burial depth of the soil increases, the active earth pressure and vertical friction between the soil and the wall continue to increase. Finally, the weight of the soil and the vertical friction between the soil and the wall reach an equilibrium state, and the soil pressure tends to a limit value. The calculation results and methods in this article can provide useful reference and guidance for the calculation of earth pressure.
