摘要
基于现有粗粒料缩尺效应的研究成果,总结缩尺方法、密实度的缩尺效应、抗剪强度、变形的缩尺效应及缩尺效应的细观研究等几个方面的研究进展,并分析其中存在的问题,就颗粒破碎对缩尺效应的影响及获取的原型级配料的性质进行探讨,指出粗粒料缩尺效应今后的发展趋势,对粗粒料缩尺效应研究及高土石坝设计提供技术支持.
Based on the research achievements of the scaling effect of the existing coarse-grained materials,this paper summarized the method,compactness effect,shear strength and deformation,and the mesoscale study of the scaling effect.The research progress and existing problems were also analyzed.Meanwhile,the influnce of particle preakage on scale effect and how to obtain the characteristics of the site gadation materials were discussed too.Further research directions of the scale effect was put forward,which provides the technical support for the study of scale effect of coarse-graind materials and design of the higher earth-rock dam.
