Field data relating to the structural failure of a long reinforced concrete cantilever retaining wall are presented. The results of a survey of the defected form of the wall are included. Analyses of the wall are carried out using classical earth pressure theories with geotechnical data. Using the measured soil parameters, the predicted bending moment at the base of the wall stem was found to be less that 5% of the actual bending moment realized. This discrepancy is due to the effects of lateral earth pressures induced by compaction. A simple method of analysis is proposed to take into account the effects of compaction. Reanalysis of the wall using this method and the measured soil parameters gives a bending moment that is in very close agreement with actual bending moment developed.
