ON THE FRICTION BETWEEN SANDS AND CONSTRUCTION MATERIALS

THE MOBILIZATION OF SKIN FRICTION BETWEEN SAND AND CONCRETE HAS BEEN STUDIED BY RUNNING A SERIES OF DIRECT- SHEAR TESTS WITH DOUBLE SURFACE OF SHEAR IN A GLASS-SIDED SHEAR BOX 44 CM LONG AND 10 CM WIDE. TWO DIFFERENT SANDS AND THREE CONCRETE-SURFACE RUGOSITIES HAVE BEEN TESTED. THE RESULTS CONFIRM THE WELL-KNOWN PHENOMENON THAT MOBILIZED FRICTION INCREASES WITH SHEAR DISPLACEMENT. THE AUTHOR SUGGESTS AN EMPIRICAL RELATIONSHIP BETWEEN THE ANGLE OF SKIN FRICTION AND THE SHEAR DISPLACEMENT. THE EXPRESSION, BECAUSE OF ITS SIMPLE FORM, COULD FIND APPLICATION IN THE TREATMENT OF SEVERAL SOIL-MECHANICS PROBLEMS INVOLVING SKIN-FRICTION DEVELOPMENT. /AMR/
