摘要
本文介绍了离散元的基本理论,提出了离散元锚杆模拟基本原理,离散元与有限元耦合计算式,并用自编D-I-1程序分析了两个典型算例。
This paper diseribes the basic theory of discrete element, give a new bolt model and introduces the coupling formulation of discrete element and finite element. In the end, several typical problems are computed by D-I-1 pregram self-drawn up.
