摘要
介绍了离散单元法的基本原理及在此基础上编写的二维离散元程序UDEC.采用UDEC对某矿节理岩体巷道锚喷联合支护效果进行数值模拟分析,得出了锚喷联合支护对节理岩体巷道支护,特别是发生楔形块体破坏时作用效果明显,同时也证实了UDEC特别适用于模拟不连续介质的大变形问题研究.
This paper introduces the basic principles of discrete element method.Universal Distinct Element Code（UDEC） was applied to numerically simulate the bolt-shotcrete effect of a certain mine’s jointed rock mass.The bolt-shotcrete support had favorable results on jointed rock mass timbering,especially on those that failure process for the wedge-shaped block.It was also confirmed that UDEC is particularly suitable for simulation of large deformation of discontinuous rock mass.
