摘要
采用刚性电液伺服机对大理石进行降低围压试验，模拟地下工程开挖过程中的围岩破碎，说明降压破碎与加压破碎在能量变化方面显著不同。
Tests of marble samples were made under depressurized pressure by using stiff electrohydraulic servo machine in order to simulate fracture of surrounding rocks in underground excavation.The results show that energy consumed changes significantly when rock samples are fractured in depressurized and pressurized conditions.
