Stability of Reinforced Retaining Walls

Abstract

The paper contains formulae for determination of reinforced soil pressure on a retaining wall when it is displaced in a foundation pit direction and in case of rigid, unmanageable wall that is in contact with soil.

Laboratory tests for determination of deformation and strength characteristics of reinforced sand soil (Е, Е_з, ν, ν_з, φ) have been carried out. Analysis of these characteristics makes it possible to conclude the fact that an increase in a relative area (α_h) of reinforced elements entails a decrease in the Poisson’s coefficients (v, Vb) and an increase in a modulus of general deformation (E).
