초록
주40시간제가 도입되면서 피크닉을 즐기는 세대가 늘어나고 있는 실정이다. 또한 가스에 의한 사고는 토요일과 일요일에 가장 많이 발생하고 있다. 2004년 10월 현재 부탄 캔으로 인한 사고는 전년 동기대비 인명피해가 1.5배로 늘어났다. 본 논문에서는 사용하고 버려지는 부탄 캔의 파열로 인한 과압의 영향에 대하여 Hopkinson의 삼승근법을 이용하여 계산하고,폭발장소 주변의 건축물과 인간에게 미치는 영향을 Probit 모델에 적용하여 피해예측을 평가하였다. Probit 모델에 적용하여 계산하면 50m 이격된 건물에는 손상여부 가능성이 전혀 없는 0
With the introduction of 40 hour working week system, more households enjoy picnics on weekends. More gas accidents take place on Saturdays and on Sundays than any other days of week. As of October, 2004 casualties resulted from butane can accidents increased 1.5 times compared to the same period of the previous year. In this study, the influence of explosion over-pressure caused by the rupture of butane can thrown away after use was calculated by using the Hopkinson's Scaling Law and the accident damage was estimated by applying the influence on the adjacent structures and people into the Probit model. As a result of the damage estimation conducted by using the Probit model, both the damage possibility of explosion over-pressure to structures 50 meters away and that of over-pressure to people 10 meters away showed nothing. The explosion efficiency used was 100 percent. As a result of this, the actual damage influenced by the rupture of butane can would be lower than the value calculated in this study and expected to be safer.
