Title: Seismic Effect of High Slope under the Action of Blasting Load and Research on Blasting Vibration Reduction Methods
Abstract: Stabilization problem of rock slope during blasting excavation is an important problem to deal with. In this paper, the blasting seismic strength rule is researched according to analysis of blasting vibration effect. The dynamic response of high slope in different media under the action of blasting and the action mechanism of blasting vibration to slope are studied. Thus mechanism of propagation of blasting seismic wave and basic principle of damping vibration during controlled blasting in rock high slope are discussed. Relativey methods of reducing vibration are put forward, such as separation and isolation of blasting vibration, dispersive charge to reduce hypocentral energy, multi-stage time delay to reduce vibration of single shot, low explosive with low density and reasonable loading structure. The methods above are combined in realistic engineering and ideal achieve are obtained.
