Numerical Simulation of Structure Dynamic Response for Civil Architecture under Mining Blasting Vibration

Abstract:

According to the geological conditions of mine and mine’s surrounding construction, the geological mechanical model of explosion area and the structure model of surrounding civil architecture were established. Based on the monitoring blasting vibration result of mining explosion process, the dynamic response character and structural stress of surrounding civil architecture which have been caused by blasting vibration of mining were studied by means of the Finite Element Method (FEM) and the method of fast Lagrangian analysis of continua three dimensions (FLAC 3D). The results show that calculated results coincide with the monitor results collectively, and the influence caused by blasting vibration on the stress and strains of civil architecture is smaller. But at the civil architecture roof, the transient amplification acceleration caused by blasting is 25%.
