为研究混合破碎岩体内流体渗透规律，利用一套由液压泵、渗透仪以及DDL 600电子万能试验机等构成的破碎岩样渗透试验系统进行了混合破碎岩样渗透特性测定，分析了混合破碎岩样与单种破碎岩样渗透特性的差异。研究表明：混合破碎岩样较单种破碎岩样的非Darcy流特性更显著；随着孔隙度的增加，单种岩样较混合岩样渗透率的变化幅度大，且相同粒径不同岩性岩样的渗透率变化程度和变化趋势呈现较大差异；随着孔隙度的增加，混合岩样的非Darcy流β因子显现减小趋势，且混合岩样较其单种岩样非Darcy流β因子的大小因粒径不同而不同。

For the seepage law research of fluid in a mixed broken rock mass,a broken rock penetration test system composed of a hydraulic pump,a permeameter and a DDL 600 electronic universal testing machine was used to test mix broken rock permeability properties,and the difference infiltration characteristics were analyzed between a mixed broken rock sample and a single sample.Research shows that the non Darcy flow characteristics of Mixed broken rock sample is more obvious than single broken rock sample,with the increase of porosity, variations in the permeability of single samples are bigger than mixed samples,and the same particle size of different lithology rock permeability variation degree and the change trend appear bigger difference,with the increase of porosity,mixed sample of non Darcyβflow factor show decreasing trend,and on the basis of different particle size,the mixed sample of non Darcyβflow factor is not necessarily greater than the single sample.
