Abstract:
Considering the effect of
reinforcement, and applying the cohesive force theory and Coulomb's earth
pressure theory, thus the tensile failure theoretical formulae of lateral soil
pressure for reinforced earth retaining wall is obtained. Analytical results
show that cohesive force of reinforced earth has increment for the tensile
failure. The lateral soil pressures value of wall back using proposed formula
are smaller than using classical earth pressure theories or variable coefficient
method. And the lateral soil pressure will increase with increasing of vertical
spacing of reinforcement and decrease with increasing of the tensile strength of
the reinforcement. The calculating results of this proposing method basically
accord with results of the site tests in geo grid reinforced earth retaining
wall.
