| 摘 要： | 强大的应力波冲击加载,能使完整介质发生变形,形成新的裂隙,导致破坏。而介质中原有的裂隙,除能提高破碎效率,还能吸收应力波的能量,使得应力波在传播过程中衰减。因此,研究应力波与裂隙的相互作用,对于研究岩石爆破机理、应力波传播规律以及波的反演--材料的动态特性等有着十分重要的意义。本文着重论述了应力波与裂隙的相互作用和裂隙对应力波传播的衰减影响,也综述了当前国内外对此所进行的模型计算和实验技术。

| Abstract: | The shock of stress waves causes deformation in intact medium, the form of new cracks and finally the failure in the material. The preexisting cracks not only help increase fracture efficiency but also absorb the energy of the stress wave to induce a decay of its propagation. Therefore the study of interaction of Stress waves with cracks will greatly contribute to the interpretation of blasting mechanism, the stress wave propagation and the dynamic behaviour of material. Our emphasis is laid on interaction of stress wave with cracks, and the influence of cracks on attenuation of the wave propagation. A view is made of the current state of model calculation and experimental technique carried out in this field. |
