摘要/Abstract

摘要： 岩体是一种高度非线性、非连续的介质，从现代工程规模来看，需要对其物理力学性质有一个比较好地认识。相比而言，数值模拟就是一个比较好的认识工具，因为其具有时间短、费用低、简单易行等优点。讨论了连续介质数值方法应用于非连续介质存在的问题，指出了非连续介质数值方法更加适合非连续介质。介绍了非连续介质数值方法中应用比较广泛、发展比较成熟的离散单元法的基本情况，比较详细地阐述了离散单元法中几个有代表性的问题，详细地介绍了离散单元法的研究进展，对其应用也做了相关的介绍，最后进行归纳总结，探讨了离散单元法今后发展的几个方向。

关键词: 离散单元法, 节理单元, 接触判断, 矢量差

Abstract: The rock mass is a nonlinear and discontinuous medium. Considered from the modern engineering scale,there should be a much better understanding of its physico-mechanical properties. Comparing with it, numerical simulation is a much better tool to know it because its merits of less time, low cost, simple manipulation. The basic situation of discrete element method which applies more extensively and develops more maturely among the discontinuous medium numerical methods is introduced, the several typical problems are expounded in detail, the researching progress of discrete element method is introduced in detail, and its relevant applications are also introduced, then the summaries are generalized, several developmental directions for the future are discussed.

Key words: discrete element method, joint element, contact identification, phasor difference, visualization
