The Analysis Of Blasting Seismic Effect Factors Based On Ansys/ls-dyna Numerical Simulation

Blasting seismic effect refers to a phenomenon that the blastingengineering of explosive chemical energy generated by the sudden release,causing the movement of the rock such as fracture, dislocation, leading to theground vibration, and the vibration in the form of wave propagation, theblasting engineering a large impact on the surrounding environment andbuildings, and even destruction. Yet the process of blasting engineering iscomplicated and changeful, blasting seismic effect is influenced by manyfactors, therefore, studies on the influence factor of blasting seismic effect isparticularly important.Through to the physical process of rock explosion and energy transfer inthe process of research, this article will discuss the mechanism of blastingseismic wave and the basic characteristics of it, and further discuss theclassification of the blasting seismic wave and the propagation and energyattenuation characteristics of blasting seismic wave. And also discusses thedifference between the blasting seismic wave and natural seismic wave.In order to further explore the damage effects on the surrounding buildingcaused by blasting engineering, what named the blasting seismic effect.Combined with the actual blasting engineering, and the existing test results,this paper discusses the factors that influence the blasting seismic and analysesthe influences of various factors on blasting seismic effect. To validate thetheoretical analysis, based on the dynamic finite element method of theparameters of the corresponding numerical simulation model is established,using the finite element software, ANSYS/ls-dyna software for different chargeconditions, the numerical simulation of blasting vibration effect, analysiscomparing the calculation results, giving us the conclusion about the Barcharge effect to reduce the blasting seismic effect.Combined with the above conclusions, the article finally stated how to reducethe blasting seismic negative effect of blasting engineering effectively, andprovide guarantee for safety of blasting projects in the future.
