The carbonated soils are different in terms of shape and form than conventional soils and silicates, and researches has shown that the behavior of these soils is subjected to different cutting with silicate soils. In this study, the particle breakage of the carbonated sand of Hormuz Island and the impact of these sands charachterestics on the behavioral parameters of soils, including the angle of friction and adhesion by experiments in a large-scale direct cutting machine. Hormoz Island's soil is used in this research because it has more crushing than other carbonate soils in the Persian Gulf region. In this research, the carbonated sands of Hormoz under condensations of 35% (loose) and 70% (dense) with two different artificial granulation (well-graded and badly degraded), yet close to their original grains Soil under 25.50, and 100 kPa overheads has been tested so that the height of the samples to obtain a model for obtaining chopping at 5 different heights (3,7,11 and 15) cm in the soil mechanics labratory of the University of Science and Technology And soil mechanics labratory of the ista-pey-filband of amol city. Then the results of the direct shearing machine are derived and by interpolating these results in different layers of the relative model for particle breakge in height, under these conditions almost the middle layer is compared to the boundary layers of relative crushing at about Two and a half times, while the internal friction angle of this layer is only about 15% of the borderline layers. In the other part of this study, the effect of speed rate on particle breakage and shear strength parameters with constant height of the device and relative density, and only by changing speed rate(0.5 mm/mim)And the overheads of this experiment have been carried out and thus the result is that at high speed rates, the speed of the crushing at about 15 percent and the angle of internal friction dropped by about 14 percent and the adhesion, which is a very small amount It is also down 14%.
