EARTH PRESSURES ON RETAINING WALLS AND ABUTMENTS: A REPORT OF THE BRITISH GEOTECHNICAL SOCIETY'S INFORMAL DISCUSSION HELD AT THE INSTITUTION OF CIVIL ENGINEERS ON JAN 13 1988

The author reports on the January 1988 Geotechnical Society's informal discussion held at the Distribution of Civil Engineers, London. The three main speakers were I F Symons and R T Murray of TRRL who presented results from pilot-scale and full-scale studies and M D Bolton of Cambridge University who discussed the development of a new design code for earth retaining structures. The pilot-scale facility described comprised both a rigid reinforced concrete wall and a movable metal wall. Studies were made of compaction pressures using full-size plant and construction techniques as well as the effects of wall movement on earth pressures. Field studies showed that relief of vertical stress caused by wall friction which could be significant with reinforced earth walls. Long-term conditions could be uncertain when using cohesive backfill and the available deflection of a more flexible wall may be taken up during the compaction process. Traffic loading effects were deliberately omitted from the proposed design code since if high residual stresses were already present due to compaction, further stress increases would generally not occur because traffic loadings were less severe than that of the compaction plant.
