根据典型岩(矿)石在不同应力波形加载条件下的冲击耗能实验结果,算出了在各种加载条件下的岩石吸能值与破碎程度。结果表明:岩石吸能与破碎效果均和加载波形有关,当施入能量足以破碎岩石时,按节能观点,钟形波加载将明显优于指数形波加载,但无论何种加载波形和加载强度,岩石的吸能均末超过入射能的50%。
According to the experimental results of impact energy consumption of typical rock (mineral) rock under different stress waveform loading conditions, the rock energy absorption and fracture degree under various loading conditions are calculated. The results show that both the energy absorption and the crushing effect of the rock are related to the loading waveform. When the energy is applied enough to break the rock, the bell-shaped wave loading will obviously surpass the exponential wave loading, but no matter what kind of loading waveform and loading strength The energy absorption of the rock exceeds 50% of the incident energy.
