Most researchers working in rock field proposed that the hopkinson system be a ideal dynamic - loading equipment and the brazilian disc be a novel specimen . according to the above , this paper suggests a new method to test the dynamic strength and dynamic fracture toughness , firstly leads the cracked chevron notched brazilian disc ( ccnbd ) which was recommended by international society for rock mechanics ( isrm ) in 1995 in testing dynamic fracture toughness , which brings in a new way in dynamic testing for rock . it is expected that the work of this dissertation will provide important basis for the further research and application of mechanical behavior of rock 结合岩石动力学领域普遍采用的动态加载设备即分离式hopkinson压杆装置和新颖的平台巴西圆盘试样,本文提出了一套测试岩石动态强度和动态断裂韧度的新方法,并首次将国际岩石力学学会( internationalsocietyforrockmechanics ? isrm )于1995年推荐的人字形切槽巴西圆盘( crackedchevronnotchedbraziliandisc ? ccnbd )试样引入动态断裂韧度的测试中,为岩石的动态断裂力学参数的测试找到了一条新的途径。
