本文应用岩石快速加载设备,系统地研究加载速率在10~(-1)～10~5公斤/厘米~2/秒范围内,花岗岩的抗压、抗拉和抗剪破坏特征,得出强度随加载速率变化的规律,并提出了花岗岩的动力破坏准则.
In this paper, the rock fast loading equipment is applied to systematically study the loading compression rate in the range of 10~(-1)~10~5 kg/cm~2/sec, and the granite’s compressive, tensile and shear damage characteristics are obtained. The law of loading rate changes, and proposed the dynamic failure criteria of granite.
