中文摘要：

根据弹塑性介质冲击波状态方程，考虑了岩石畸变的影响，加入岩石的非线性弹塑性本构关系，组成了冲击波在高压岩石介质传播的状态方程组。然后根据波阵面两侧各状态量的变化，分析了冲击波在高压塑性硬化岩石介质中传播的波阵面波形突跃规律，同时分析了冲击波在由低压岩石介质向高压岩石介质传播过程中的应力幅值突跃规律，并建立了介质压力与冲击波幅值的关系式。研究成果为预防灾害发生及制定防冲措施提供了理论依据。

英文摘要：

According to the state equation of shock wave in elastic-plastic medium, the state equation set of shock wave in high-pressure of rock was formed by adding the non-linear elastic-plastic constitutive relation of rock, simultaneously, the effect of rock distortion was considered. Then, based on the changes of some state variables pre and post of wavefrent, waveform jump law of shock wave transmitted in the high-pressure plastic hardening rock was studied, the relation formula of and medium＇s pressure and shock amplitude was also studied when shock wave trans- mitting from low pressure state medium to high pressure state medium. Moreover, the relationship between medium pressure and shock wave amplitude was established. The results provided a theoretical basis for the prevention of disasters and preventing rock burst measures.
