경남 창원시 진해 지역의 발파진동 예측에 관한 연구

다국어 초록 (Multilingual Abstract)

Vibration problems due to a number of construction works including blasting for infrastructure development are getting important because of a civil appeal. Vibration is representative factor of environmental damage, hence, this has great meaning to prevent potential disasters. In this study, through the real-scale test blasting performed at Jinhae area, Changwon, Gyeongnam, the diameter of blasted rock was analyzed with blasting method, and square root equation(SRE) with 95% confidence level was proposed for prediction of blasting-induced vibration. From the comparison between tendencies of blasting-induced vibration with distance, it was confirmed that the predicted blasting-induced vibration by USBM(U.S. Department of Interior, Bureau of Mines) equation was more conservative than that by proposed equation based on the real-scale test blasting. Therefore, measuring vibration and determining
equation for prediction of blasting-induced vibration through the real-scale test blasting are needed for optimal blast design considering field condition. However, in the case of real blasting including tunnel excavation, measuring vibration is required for damage prevention to surrounding facilities.
