摘    要:爆破荷载是导致边坡失稳的重要外部因素。与土质边坡相比,由于节理面的存在,爆破荷载下岩质边坡稳定性研究更加复杂。综述节理对爆破应力波传播特性的影响规律以及爆破荷载作用下岩质边坡数值计算要点,并从岩质边坡自身特点、爆破应力波振动特性以及爆破荷载与其他外界因素耦合3方面详述岩质边坡动力稳定性研究现状,总结得出节理力学性质及分布,爆破应力波振动速度、频率及其衰减规律等因素是岩质边坡极其重要的稳定因素。最后,对爆破荷载作用下岩质边坡稳定性研究进行展望,为进一步深入研究奠定基础。

关 键 词:爆破荷载  应力波传播  节理  岩质边坡  动力响应  边坡稳定

Abstract:Blasting load is an important external factor of slope instability.Due to the joint wall,the stability of rock slope under blasting load is more complicated than that of soil slope.The effect of joint on the stress wave propagation and several key points of numerical calculation of rock slope under blasting load are summarized.Furthermore,the current status of the research on the dynamic stability of rock slope is reviewed from three aspects:the characteristics of rock slope,the characteristics of blasting stress wave and the coupling of blasting load.It is concluded that the mechanical properties and distribution of joints,and the vibration velocity,frequency and attenuation law of blasting stress wave are the most important factors for the stability of rock slope.In the end,the further research on the stability of rock slope under blasting load is prospected,which lay a foundation for intensive studies on dynamic stability of rock slope.
Keywords:Blasting load  Stress wave propagation  Joint  Rock slope  Dynamic response  Slope stability
