SIDE FRICTION IN MODEL RETAINING-WALL EXPERIMENTS

This paper examines the effect of friction between soil and the sides of the sample box on data obtained from plane strain earth pressure tests on model retaining walls in sand. The relevant literature is reviewed and it is concluded that the side friction can have a significant effect on the measured forces. A new method of calculation, based on that of Sokolovski, is developed to provide a quantitative estimate of the magnitude of the effect of friction. The computational method is described and the results of calculations for a number of active and passive cases are presented. It is found that the effects of side friction are greatest when the sides of the sample box are rough, the angle of internal friction is high, the wall is relatively narrow, and the sand is subjected to passive failure. The small effects of side friction on observed deformations are considered. /Author/
