英文摘要：
The advantages and disadvantages of different scale methods for laboratory tests on coarse-grained materials were summarized. The existing apparatuses for strength and deformation tests on coarse-grained materials as well as the representative achievements were reviewed. The achievements in researches on the scale effects on the strength and deformation properties of coarse-grained materials were discussed. The basis for the evaluation of the scale effects was analyzed. Problems in the studies on scale effects were presented, including density control and quantitative expression of the scale effects. It is pointed out that much attention should be paid to the density control of the substitute and original gradation soils in studies on the scale effects.
