ESTIMATION OF N-VALUE USING PRESSURIZED SAND TANK AND VERIFICATION OF VERTICAL LOADING TEST OF MODEL PILE

Abstract

The N-value of soil in the pressurized sand tank was necessary for comparing the results of loading test on model pile and actual pile. The relationships between relative density after pressurizing the soil, vertical loading pressure and the N-value were obtained from the standard penetration test in the tank. Using these relationships, the relationship between the bearing capacity of the model pile and the N-value was determined. By comparing this relationship with similar relationships obtained from the loading tests of actual pile, the results of model loading test using the tank and those of the standard penetration test were validated.
