Sažetak
A specially equipped pullout apparatus, size 1.9 x 0.9 x 1.2 m, has been developed to measure the soil-grid interaction during pullout. The method used to evaluate the soil-grid interaction is a veritable novelty as the velocity of shear waves passing through the specimen is measured from top to bottom. This measurement is performed at different levels around the grid in order to obtain a velocity profile in the soil adjacent to the grid. Specially adapted accelerometers, positioned at different distances above and below the grid, are used to measure an arriving time of propagating compressive and shear waves through reinforced soil. Once the velocity of the wave is known, the shear (Go) and elastic (Eo) moduli (at small strains) are calculated for these depth intervals. Some results of this study are presented, and the testing apparatus and technology are described.
