颗粒形状对多孔介质孔隙特征和渗流规律影响研究的探讨

摘要

This paper discusses the possible influence of grain shapes on the pore system of porous media and its seepage rules, as well as its research significance. By reviewing research results in related areas, discussions were made on the measurement method of grain shape, simulation method of grain shape and grain packing, visualization method of pore system, and experimental comparison method of seepage rules. The research result helps demonstrate the prospect of developing filter materials for water treatment and applying aggregate for dam construction.%讨论了颗粒形状对于多孔介质孔隙系统及其渗流规律的可能影响及其研究意义;综述相关领域的研究成果,探讨了颗粒形状的测量评定方法、颗粒形态和填筑的模拟方法、孔隙系统的可视化研究方法,以及渗流规律的试验对比研究方法;分析指出了颗粒形状对渗流规律影响的研究在促进水处理滤料开发和碎石料作为大坝填料利用方面的应用前景.
