The historical developments of triaxial SHPB apparatus were reviewed and the characteristics of various types of testing machines were compared. A comprehensive analysis of related research literatures on triaxial SHPB tests and some common conclusions were summarized: (1) the dynamic compressive strength of rock will increase with a linear or exponential function as strain rate increases under a constant confining pressure, the brittleness of rock will reduce while plasticity increases; (2) a significant linear relationship is shown between the dynamic compressive strength of rock and confining pressure when strain rate is in a certain circumstance; (3) the compressive strength coupled dynamic and static loads shows a similar linear-increase trend with the increase of confining pressure under a constant axial pressure, while it shows a rising trend firstly and then decline with axial pressure increasing under a constant confining pressure. However, due to the characteristics of triaxial SHPB apparatus and the rock material itself, some basic issues, such as stress loading waveform, the sample size requirements, there is no uniform test specification for tests. Many results of historical documents can only be compared qualitatively and don't be analyzed on a unified scale. In the future, developing an international suggested method about triaxial SHPB test will be a key work., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=岩石材料的三维动力特性试验研究是岩石冲击动力学中很重要的一个领域，也是目前研究的一个热点。本文论述了三轴SHPB岩石力学试验机的研制情况，对各类试验机的特点进行了比较。综合分析了三轴SHPB试验相关研究文献，总结了一些共有规律：① 在围压一定的情况下，岩石的动态抗压强度会随着应变率的增加而增加，呈现出线性函数或者指数函数增加形式，并且脆性减弱，塑性显著增加；② 在应变率一定的情况下，岩石抗压强度会随着围压的增大而增大，线性关系比较显著；③ 岩石动静组合加载时，在轴压一定时，岩石的动静组合抗压强度会随着围压的增大而增大，呈现出近似线性增加趋势；在围压固定时，抗压强度随着轴向静压的增大呈现出先增大后减小的趋势。由于SHPB试验装置和岩石材料本身的特点，目前在一些基本问题上，如加载应力波形、试样尺寸要求等方面，还没有统一的试验规范要求，很多试验结果只能进行定性比较，无法在统一尺度上进行定量分析。最后，针对该领域的发展趋势进行了论述，指出尽快建立一套国际性的建议试验方法是将来的一个关键问题。,
