THE INFLUENCE OF STRAINS IN SOIL MECHANICS

THE AIMS, DURING THE PAST 20 YEARS, OF THE CAMBRIDGE RESEARCH PROGRAM IN SOIL MECHANICS ARE OUTLINED. THE PRINCIPAL OBJECTIVE IS TO DEVELOP AN UNDERSTANDING OF THE STRESS-STRAIN BEHAVIOR OF SOILS SO THAT RELIABLE PREDICTIONS CAN BE MADE CONCERNING THEIR LOAD-DEFORMATION CHARACTERISTICS AT ALL WORKING LOADS, RATHER THAN ONLY AT FAILURE, IN PRACTICAL PROBLEMS. A SUPERSTRUCTURE AND ITS FOUNDATION CAN THEN BE DESIGNED AS A UNIT. THE PRESSING NEED FOR THE STUDY OF THE LOAD-DEFORMATION BEHAVIOR OF SOILS IN MIXED BOUNDARY VALUE PROBLEMS AT MODEL SCALE IS EMPHASIZED. NEW VERSATILE SHEAR TEST EQUIPMENT WHICH CAN IMPOSE A WIDE RANGE OF STRESS AND/OR STRAIN PATHS, TOGETHER WITH NON-DESTRUCTIVE METHODS OF CHECKING THE UNIFORMITY OF THE BEHAVIOR OF SPECIMENS, ARE BRIEFLY DESCRIBED. TYPICAL DATA ARE PRESENTED FOR ONE PROBLEM, ILLUSTRATING THE VARIATION OF THE PASSIVE PRESSURE ON A RETAINING WALL WITH THE DISPLACEMENT OF THAT WALL INTO SAND. A REVISED STATEMENT OF THE MOHR-COULOMB FAILURE CRITERION IS PROPOSED. /AUTHOR/
