| 摘 要： | 散粒体斜坡俗称“溜砂坡”,对其运动和堆积特征的研究是溜砂坡防治的关键.在斜坡模型架上模拟碎块石的运动过程和堆积过程,探索其颗粒大小、形态与斜坡角的关系.通过堆积体纵剖面取样发现,溜砂坡堆积呈现分形结构,其颗粒质量粒径分布分维数随黏粒含量的增大而增大.

| Abstract: | To study the movement and accumulation characteristics of the sand-sliding slope is the key to its prevention and treatment.The movement and accumulation process of broken stones was simulated on a slope model to study the relationship of particle size and shape with slope angle.The profile sampling made clear that the sand-sliding accumulation body presents a fractal structure and fractal dimension increases with sticky grain content increasing. |

| Keywords: | sand sliding slope accumulation characteristics stratification fractal dimension |
