【摘要】 颗粒的迁移对地下水中污染物的迁移起着重要的作用。本文以扎塘赤泥库为例,通过现场采样和室内实验分析相结合的方法,分析了扎塘赤泥库赤泥颗粒的分布特征及赤泥颗粒的迁移规律。分析结果表明:赤泥为一种级配良好的类黏性土回填物;不同取样深度上,赤泥颗粒的分布特征基本趋于一致,不同粒径范围的赤泥颗粒迁移的规律存在着差异,水动力条件对赤泥颗粒迁移的最大粒径起着决定性的作用。。更多还原

【Abstract】 Particles transport plays an important role in contaminants transport in groundwater. In this study,the case of red mud pond in Zhatang is taken to analyze the distribution characteristics and transport law of red mud particles by means of combining site sampling and laboratory analysis. The results suggest that red mud is a kind of back-fill material that is similar to clay with well-graded. The distribution characteristics of red mud particles tend to be consistent at different sampling depths. There are differences in the transport law of red mud particles between various particle sizes. Hydrodynamic conditions play a decisive role in the maximum particle size of red mud particles in transport process.更多还原
