STUDY OF SANDS BEARING CAPACITY IN MODEL TESTS

RESULTS ARE PRESENTED OF MODEL TESTS, SIMILAR TO LOADING TESTS, DONE WITH SEVEN SAND SAMPLES. FIVE SAND SAMPLES WERE OF UNIFORM SANDS WHOSE MAIN DIFFERENCE WAS IN THE SIZE OF GRAINS; ONE SAMPLE WAS OF WELL GRADED SAND WITH GRAINS OF A SHAPE LIKE THE ONES IN THE FORMER SAMPLES; AND ONE OF THE SAMPLES HAD THE SAME GRADING AS ONE OF THE FIRST FIVE, BUT DIFFERENT IN THE SHAPES OF GRAINS. THE SAMPLES WERE TESTED IN DIFFERENT COMPACTION STAGES. THE ANALYSIS OF THE RESULTS, BASED ON THE PRESSURE-SETTLING DIAGRAMS, SHOWED THAT THE SIZE OF THE GRAINS HAD LESS INFLUENCE ON THE BEARING CAPACITY THAN THE RELATIVE COMPACTION, THE GRADING DISTRIBUTION AND THE SHAPE OF GRAINS. TESTS OF PENETRATION RESISTANCE WITH THE SAME SAMPLES, SHOWED THAT IT IS THE BEARING CAPACITY AND NOT THE RELATIVE COMPACTION, WHICH IS BETTER CORRELATED TO THE PENETRATION RESISTANCE. A REVIEW OF THE SEVERAL FOUNDATION CODES SHOWED THAT THE CANADIAN CODE IS THE ONE WHICH IS MORE IN ACCORDANCE WITH THE RESULTS OF THE RESEARCH. SPECIAL TESTS WERE MADE TO JUSTIFY THE APPROXIMATIONS IN THE CODES. /RRI/
