摘要
该文概述了岩土体颗粒破碎的理论研究价值及工程意义。结合颗粒破碎物理试验研究现状,综合阐述了目前数值模拟技术的优势和方法,并认为离散元方法的数值模拟可以更有效地对岩土体颗粒破碎进行研究。总结分析了在离散元方法中研究颗粒破碎的两种方法,黏结模型和颗粒破碎模型。
This paper outlines the significance of particle breakage of rock and soil in theory and engineering.Combined with the present experimental study on particle breakage of physics,synthetically expounds the advantages of the numerical simulation technology,and the method of DEM can be more effective to study the？particle breakage of rock and soil.Two methods of particle breakage in DEM was summarized and analyzed,the bond model and the particle failure criterion.
