Abstract:
VARIOUS LOAD BEARING TEST TECHNIQUES ARE ANALYZED, BOTH THEORETICALLY AND EXPERIMENTALLY, IN AN ATTEMPT TO INTEGRATE THE EFFECTS OF THE MANY VARIABLES THAT INFLUENCE THE BEARING CAPACITY AND LOAD-DEFORMATION CHARACTERISTICS OF SOILS. CONSIDERABLE USE IS MADE OF THE METHODS OF DIMENSIONAL ANALYSIS. THE PHYSICAL VARIABLES CONSIDERED INCLUDE THE SETTLEMENT OR PENETRATION OF THE LOADING PLATE OR PISTON, APPLIED FORCE, SIZE AND SHAPE OF THE PLATE OR PISTON, METHOD OF TESTING, TIME OF LOADING, NUMBER OF LOAD APPLICATIONS, AND THE PROPERTIES OF THE SOIL BEING TESTED. CORRELATION BETWEEN THE LOAD-DEFLECTION RELATIONS FOR LOAD BEARING TESTS AND THE SOIL STRESS-STRAIN CURVES OBTAINED FROM TRIAXIAL AND UNCONFINED COMPRESSION TESTS ARE GIVEN. LABORATORY AND FIELD DATA OBTAINED FROM VARIOUS LOCATIONS THROUGHOUT NORTH AMERICA ARE ANALYZED AND INTERPRETED. ATTENTION IS GIVEN TO CORRELATION OF RIGID PLATE BEARING TESTS AND THE CALIFORNIA BEARING RATIO TEST. /HRB/
