C. B. R. TEST UNDER LATERAL PRESSURE

IT IS KNOWN THAT LABORATORY AND FIELD TESTS YIELD DIFFERENT C. B. R. VALUES FOR GRANULAR MATERIALS. THIS IS DUE PRIMARILY TO THE HIGHER LABORATORY STRENGTH OF THE SPECIMEN CONFINED IN A RIGID CYLINDER. A LABORATORY PROCEDURE IS OUTLINED, BY WHICH SPECIMENS ARE SUBJECTED TO CONTROLLED LATERAL PRESSURE, AND A FORMULA IS PROPOSED FOR DETERMINING FIELD VALUES FROM LABORATORY DATA ON THE BASIS OF THEORETICAL BEARING-CAPACITY CONSIDERATIONS. TEST RESULTS FOR TWO MATERIALS ARE REPORTED. /RRL/AUTHOR/
