| 摘 要： | 砂砾石填料的渗透特性与颗粒的形状、大小及分布特征关系密切。通过试验对渗透系数与填料的级配、粒径不均匀性的关系进行了研究分析．并为工程设计提供了合理的砂砾石填抖级配，达到了在保证强度的情况下增强渗透能力的目的。

| Abstract: | Permeability performance of rockfill is closely related to the particle shape, particle-size and its distributing characteristics. So the seepage rate and statistical characteristics of rockfill particles can be organically combined together. Changing the gradation rationally is a feasible method to control the seepage ability of rockfill in engineering. |
