Lateral Earth Pressure behind Walls Rotating about Base considering Arching Effects

Abstract EN

In field, the earth pressure on a retaining wall is the common effect of kinds of factors.

To figure out how key factors act, it has taken into account the arching effects together with the contribution from the mode of displacement of a wall to calculate earth pressure in the proposed method.

Based on Mohr circle, a conversion factor is introduced to determine the shear stresses between artificial slices in soil mass.

In the light of this basis, a modified differential slices solution is presented for calculation of active earth pressure on a retaining wall.

Comparisons show that the result of proposed method is identical to observations from model tests in prediction of lateral pressures for walls rotating about the base.
