| 英文摘要 | The particle shape is a key factor in the strength and compatibility of granular material. To investigate the evolution of the particle shape of two kind of sands. The quartz sand from Fujian and the calcareous sand from the South China Sea, were chosen for ring shear tests. The sieving method and laser grain-size analyzer were used to obtain the particle size distribution, and the microscope technique were employed to characterize the particle shape in terms of roundness and flatness. The experimental results indicate that the change of the particle size of the calcareous sand is more significant than the quartz sand. The roundness and flatness of the calcareous sand particles decreased obviously while the roundness of the quartz sand was scarcely changed and the flatness increased. It is shown that the large displacement shear makes the calcareous sand more rounded and quartz sand more roughed. |
