中文摘要	为了研究土石坝中不同材料间接触面的力学特性,利用清华大学土与结构物接触面循环加载剪切试验机,对粗粒料与混凝土板接触面分别进行了试样缩尺和粒径缩尺试验,得到了缩尺前后的接触面强度与变形特性。根据试验结果,探讨了试样缩尺和粒径缩尺对接触面力学特性的影响,并分析了其机理。结果表明:当试样与粗粒料最大粒径之比大于一定值时,试样缩尺的影响很小;而粒径缩尺后的接触面强度会降低,同时初始剪切模量则有所增长,其影响不能忽略。; The mechanical behavior of the interfaces between various granular materials in earth-rockfill dams was analyzed using sample scaling and size scaling tests for the interface between coarse-grained materials and a concrete slab using a cyclic shear test machine for soil-structure interfaces at Tsinghua University. The tests illustrated the strength and deformational behavior of the interfaces before and after scaling for analyses of scaling effect on the mechanical behavior. The test results indicate that the sample effect is neglectable if the ratio of the sample size to the maximum size of the coarse-grained material is large. However, the interface strength decreases after size scaling while the initial shear modulus increases, which cannot be ignored.
