154kV 대신 S/S인출 전력구 시험발파 패턴 및 진동, 소음 계측에 의한 기존 CRACK에 미치는 영향 연구
On the Study of Blasting Vibration, Sound by Measuring Gage Influence to Exist Crack in 154kV Daeshin Electric Cable Tunnel
초록
This area is covered in Andesite of high compression strength and located in PUSAN SEO-KU. There are many old houses around shaft site. So, we must have a cautious blasting operation. A total of 40 blasts were test at DAE-SHIN Shaft site to study the magnitude and frequency characterization of blast-induced vibration. The effect of viblating frequency on structual damage and site-specific scaling to define th empirical equations were also discussed. The result can be summarized as follows: 1. Some empirical equations were obtained.
