Experimental Study on the Propagation Characteristics of Blasting Vibration in Layered Rock Masses

Abstract

ABSTRACT Blasting vibration propagates anisotropically in the layered rock mass. Combined with a typical engineering case, propagation and attenuation characteristics of blasting vibration along different propagation paths were studied based on the blasting experiment and vibration measurement result. According to the analysis result, the engineering area was classified into vibration-sensitive region, surrounding region and general region considering their different influences on the protected buildings. To comply with the vibration velocity control requirements, the blasting parameters for different regions were specifically proposed so as to ensure the safety of the neighboring building and the construction period of the project.The analysis method of blasting vibration test can provide a useful and important reference for the similar construction cases.
