INVESTIGATION OF PILE RESISTANCE BY COMBINED SOUNDING

EXPERIMENTAL WORK IS DESCRIBED WHICH WAS CARRIED OUT BY THE SCIENTIFIC RESEARCH INSTITUTE OF FOUNDATIONS AND UNDERGROUND STRUCTURES AT SEVERAL SITES AND INVOLVING THE INVESTIGATION OF THE RESISTANCE OF REINFORCED CONCRETE PILES BY MEANS OF THE COMBINED SOUNDING METHOD. THE PRINCIPAL ASSUMPTIONS USED AS THE BASIS OF THIS METHOD ARE EXPLAINED AND BRIEFLY DESCRIBED. THE RESULTS OF THE DETERMINATION OF THE RESISTANCE OF REINFORCED CONCRETE PILES BY THE METHOD OF COMBINED SOUNDING AND A COMPARISON OF THESE RESULTS WITH THOSE OBTAINED BY TESTING THE SAME PILES WITH STATIC LOADS IS PRESENTED, AND FORMULAE FOR CALCULATING THE RESISTANCE OF PILES BY THE METHOD OF COMBINED SOUNDING ARE GIVEN. FIELD AND LABORATORY TESTS HAVE CONFIRMED THE INITIAL ASSUMPTIONS THAT THE SPECIFIC RESISTANCES OF THE LOWER END AND THE SIDE SURFACE OF PILES THAT ARE SUBJECT TO VERTICAL LOADS DEPEND MAINLY UPON THE PROPERTIES OF THE SOIL SURROUNDING THE INDIVIDUAL PILE AND NOT ON THE DIMENSIONS OF ITS CROSS-SECTION. THE RESULTS OF THESE INVESTIGATIONS PERMIT THE USE OF COMBINED SOUNDING FOR DETERMINING THE RESISTANCE OF PILES, INSTEAD OF LABOR-CONSUMING AND EXPENSIVE PILE LOAD TESTS. /LCPC/RRL/A/
