简单介绍了分离式霍普金森压杆装置及其工作原理，从不同种类的岩石、不同环境参数条件下的岩石以及岩石破坏机理的角度对岩石动态力学性能的研究现状进行了综述与评价，指出现有的研究主要还是试验研究，对金刚石加工石材过程中的切削力和已加工表面质量等物理量的测量以及对石材加工过程中材料去除机理的研究相对较少。继而讨论了石材本构与加工过程物理量的关系，得出石材的动态力学性能应用于其加工过程物理量的预测是可行的结论，并指出如何利用石材的动态力学性能以及相适应的数值仿真手段，对冲击作用、岩石微观组织演变和应力变化这三者之间的作用机制，失效机制等相关理论进行研究将是个非常重要的研究方向。

This article gives a brief introduction to the Split Hopkinson Pressure Bar appa-ratus and its operating principle.Current research status of dynamic mechanical proper-ties of rock has been summarized and evaluated from various of viewpoints such as differ-ent types of rocks,rocks under different environmental parameters and the failure mecha-nism of rock.The conclusion is that the current research is a kind of experimental study. It has relatively small amount of research for the cutting force during the stone processing by diamond,the material removal mechanism during the stone processing and the meas-urement of physical quantities such as machined surface quality.The relationship between constitutive of stone and its physical quantity during processing has also been discussed. It comes a conclusion that the application of dynamic mechanical properties of stone to forecast the physical quantity during its processing is workable.This article also points out that the research of application of dynamic mechanical properties of stone and the suit-able numerical simulation method,mechanism of action between impact effect,rock mi-crostructure evolution and variation of stresses and the related theories such as the failure mechanism will be the very important research fields.
