提出了岩石声发射规律数值模拟的基本设想和框架，并以有限单元法为例就具体实施的几个关键问题作了简述，包括单元的划分、单元参数的赋值、声发射率的计算。本文给出了一个计算实例，所得结果包括岩石声发射的时间序列和空间序列分布。 The basic assumption and framework of numerical simulation of acoustic emission law are put forward, and some key problems of concrete implementation are described by using finite element method as an example. It includes unit division, unit parameter assignment and acoustic emissivity calculation. In this paper, a calculation example is given, and the results include the time series and spatial series distribution of rock acoustic emission.
