【摘要】 从爆破地震效应分析入手,对实验室内混凝土边坡的爆破振动进行试验研究,探讨爆破振动在边坡中的传播规律,并分析了边坡爆破振动对边坡作用机理和地震强度的影响。结果表明,人工预留的预裂缝作为减震沟有明显的减震效果,且表明可运用于实际的边坡爆破工程。更多还原

【Abstract】 Beginning with a discussion of seismic effect,this paper presents an experimental study of blasting vibration of concrete slope in the laboratory,investigates the propagation of blasting vibration in the slope,and analyzes the mechanism of blasting vibration acting on the slope and the effect of vibration intensity.The result shows that the damping effect is obvious when the man-made reserved pre-split crack is used as damping ditch,and the man-made reserved pre-split crack can be applied to the practice of slope blasting engineering.更多还原
