摘　　要：针对乐园水库泥岩心墙防渗料进行一系列的室内土工试验,研究了泥岩心墙防渗料的颗粒级配、渗透、压缩及剪切强度等特性,提出了泥岩心墙防渗料的合理级配范围和压实控制干密度,论证了建议级配范围内的泥岩心墙防渗料具有良好的抗渗性能和力学性能。A series of indoor geotechnical tests are carried out against the impervious material for mudstone core wall at Leyuan Reservoir to the extent that the particle size distribution, seepage, compressive and shearing strength thereof are studied. Then the proper distribution range and dry density for compaction control are proposed and within this range recommended, the impervious material is proved to have good seepage resistance and mechanical properties.
