利用分离式霍普金松压缩试验装置和自制的加热炉，对辉长岩和大理岩短棒圆柱试件进行了（100～300℃）状态下的动态（冲击）断裂试验，同时，为了帮助确定加热条件下岩石失稳断裂时间，还借助于动态云纹方法进行了室温条件下岩石动态断裂失稳时间的判定。上述试验研究表明，两种岩石在冲击加载条件下的断裂韧度均随加载率增加而增加，而断裂韧度随加热温度的变化并不明显。
Using a split Hopkinson compression test apparatus and a self-made furnace, a dynamic (impact) fracture test was performed on gabbro and marble short rod cylindrical specimens (100 to 300°C), and in order to help determine Under the condition of heating, the unstable fracture time of the rock was determined by dynamic moire method. The above experimental study shows that the fracture toughness of two kinds of rock under impact loading increases with the increase of the loading rate, but the fracture toughness does not change significantly with the heating temperature.
