摘　　要：针对王家沟水库沥青混凝土心墙堆石坝工程进行一系列的室内土工试验,研究了过渡料的颗粒级配、渗透性、压缩性及剪切强度等特性,提出了合理的过渡料级配范围和压实控制干密度,论证了建议级配范围内的过渡料具有良好的抗渗稳定性和力学性能。A series indoor geotechnical tests are carried out against the rock-fill dam with asphalt core wall in Wangjiagou Reservoir and the properties of the transitional material, such as the grain concrete grading, penetrability, compressibility and shearing strength, are studied so that the proper grading limit, compaction control and dry density thereof are suggested. It is proved that the transitional material in the range of grading limit proposed has good anti-seepage stability and mechanical properties.
