There is a widespread concern over the study of seismic safety with explosive source as time goes on. As far as explosive source itself is concerned, the selection of charge size and well depth has the much effect on excitation energy and frequency. So in the view of the same well depth and different charge sizes, we selected a site for a field experiment to study the seismic safety with explosive source. Aecelerograms of every explosion were observed by acceleration meter. Measurements were conducted with the accelerometers that were laid on the basement, windowsill, and rooftop. Acceleration was transformed to velocity in order to correspond with the Safety Regulations for Blasting, and analysis was conducted to the measured data that was acquired from the rooftop. It presents the analysis of structural response, safe distance, vibration frequency in explosive source to study the structural response. We discussed the seismic safety and offered references, which can help direct field-seismic gathering, increase seismic safety and minimize economic expenditure.[著者文摘]
