Abstract: A series of non-linear dynamic response analyses of a cantilever retaining wall were performed to assess the appropriateness of the Mononobe-Okabe method for determining the seismically induced lateral earth pressures on the stem of the wall. For the wall analyzed, it was found that at very low levels of acceleration the induced pressures were in general agreement with those predicted by the Mononobe-Okabe method. However, as the accelerations increased to those expected in regions of moderate seismicity, the induced pressures are larger than those predicted by the Mononobe-Okabe method. This deviation is attributed to the flexibility of the retaining wall system and to the observation that the driving soil wedge does not respond monolithically, but rather as several wedges.
