Abstract

The influence of the over-pressure caused by Explosion in gas station was calculated by using the Hopkinson's scaling law and injury effect by accident to buildings and human bodies was estimated by applying the probit model. As a result, the injury estimation was conducted by using the probit model for leakage 10% of 20ton storage tank. The separate distances from LPG station for building(damage) and human(lung hemorrhage to death) are 260 and 30 meters, respectively.

LPG 충전소에서 발생하는 폭발의 피해를 Hopkinson의 삼승근법을 이용하여 계산하고, 건물과 인체에 미치는 영향을 프로빗 모델에 적용하여 피해예측을 평가하였다. 현재 국내에서 가장 많이 운용하는 20ton 저장탱크를 대상으로 누출량 10%를 프로빗 모델에 적용하여 계산하면 LPG 충전소에서의 안전거리는 각각 건물(손상)은 260m 이며, 인체(폐출혈 사망)는 30m이다.
