【摘要】 本文记述了模拟野外地壳应力场的室内水压致裂真三轴实验中,岩石产生声发射时的注入压力和岩石破坏时的注入压力的对应关系,以及声发射频率、幅度等方面的表现,记述了岩样在零切向应力及负切向应力时对应的破裂压力。从而得出岩石在水压致裂过程中表现出与其它实验方法不同的一些特性的结论,进一步加深了对岩石性质的认识,这对于预测岩石在工程和地震中的行为都有重要意义。更多还原

【Abstract】 This paper gives a description on the corresponding relationship between the injection pressure at rock breakage and that at sound emission,behavior of the frequency and amplitude of sound wave,and gives fracturing stresses corresponding to zero or negative tangential stress respectively.A conclusi- on that some rock characteristics exhibited in the hydrofracturing process are different from those obtained by other experiment techniques is reached,A more detailed recognition of the rock properties will be important in the pr- ediction of behavior of rocks in both engineering and earthquake problems.更多还原
