Abstract

In order to ensure the safety and stability of sand-mudstone interbedded rock slope under blasting vibration, it is necessary to clarify the attenuation law of blasting vibration in sand-mudstone interbedded rock slope. Based on the first-stage project of Pinglu Canal Youth Hub, through the field blasting test, the fitting results of the blasting vibration attenuation model before and after the elevation effect correction were compared and analyzed, and the blasting vibration attenuation law of the sand-mudstone interbedded rock slope was deeply studied. The results show that the maximum displacement of slope rock mass under blasting vibration produces elevation amplification effect, and the final displacement may not be zero. The fitting accuracy of a blasting vibration attenuation model considering the elevation effect is higher than that of the unmodified Sadoevsky formula, and the elevation effect should be considered in the blasting vibration attenuation law of rock slope. There are differences in the attenuation law of blasting vibration for the sand-mudstone interbedded rock slope with different tendency and dip angles of beddings. It is an important research direction to establish the attenuation law of blasting vibration for different beddings.
