The preliminary design of free embedded cantilever walls in granular soil

This paper describes new model wall experiments which were undertaken at the University of Surrey. Their aim was to provide further data on the performance of free embedded cantilever walls in granular soil. These experiments used a simplified technique which consisted of modelling only the segment of wall which was situated below the excavation level. These results fit well with a previously normalized data set. The trend of increasing bending moment with depth of embedment, for a constant plane strain angle of internal friction, which was postulated on the basis of the previously available experimental results, is confirmed. These data have been re- interpreted in the form of charts, which the authors suggest may be used for preliminary design purposes. For the covering abstract see IRRD 860485.
