The discusser read with interest the paper by Diakoumi & Powrie (2013) proposing an interesting method for the analysis of propped flexible retaining walls based on the mobilisation of active and passive pressures on the wall due to movement of wall segments. An assumed deformation mechanism within the soil is used to estimate the strain associated with rotation of a particular wall segment. This mechanism is then superposed for each wall segment, the resulting earth pressures are calculated; the equality between the wall bending moments implied by equilibrium and those required to achieve the appropriate bending of the wall is used to calculate the rotation of each segment. Although the method of analysis provides insight into the conservatism of conventional design calculations for different wall flexibilities, there are two aspects of the paper which provoke further discussion.
