DEFORMATION OF WALLS RETAINING SOFT CLAY BACKFILLS

RESTRAINT OF A RETAINING WALL HAS BEEN INVESTIGATED BOTH EXPERIMENTALLY AND THEORETICALLY. A RIGID MODEL WALL RETAINING A SOFT CLAY BACKFILL WAS ALLOWED TO YIELD BY REDUCING THE LATERAL SUPPORT ON THE WALL. OBSERVATIONS WERE MADE OF THE AMOUNT AND RATE OF LATERAL WALL DEFORMATION. THESE OBSERVATIONS INDICATED THAT THE RATE OF WALL MOVEMENT WAS INVERSELY PROPORTIONAL TO THE LATERAL RESTRAINING FORCE AND, FOR THE VERY SOFT CLAYS, THE RATE OF WALL MOVEMENT FINALLY BECAME CONSTANT. PREDICTIONS OF THE WALL DEFORMATION AS A FUNCTION OF TIME WERE MADE BY MEANS OF THE RATE PROCESS THEORY SUPPORTED BY DATA FROM A SERIES OF TORSION SHEAR TESTS. THESE THEORETICAL PREDICTIONS WERE IN REASONABLE AGREEMENT WITH THE OBSERVATIONS. /AUTHOR/
