Abstract

This study proposed a prediction equation for the estimation of blasting vibaration and blasting noise, utilizing 320 datasets for the blasting vibration and blasting noise acquired during urban blasting works in the Incheon, Suwon, Wonju, and Yangsan regions. The proposed blasting vibration prediction equation, derived from regression analysis, indicated correlation coefficients of 0.879 and 0.890 for SRSD and CRSD, respectively, with an R2 value exceeding 0.7. In the case of the blasting noise prediction equation, stepwise regression analysis yielded a correlation coefficient of 0.911 between the prediction values and real measurements for the blasting nosie, and further analysis to determine the constant value revealed a correlation coefficient of 0.881, with an R2 value also exceeding 0.7. These results suggest the feasibility of applying the proposed prediction equations when environmental impact assessments or education environment evaluation according to urban development or apartment construction projects is performed.

본 연구는 인천, 수원, 원주, 양산 지역에서 발파작업 동안 취득한 320개의 발파 진동 및 발파 소음 데이터를 사용하여, 발파 진동 및 발파 소음 추정에 적용가능한 예측식을 개발하였다. 발파진동 예측식은 회귀분석결과, SRSD 및 CRSD에 의한 상관계수가 각각 0.879, 0.890이며 두 경우 모두 R2 ≥ 0.7로 나타났다. 발파소음 예측식은 단계적 회귀분석을 수행한 결과, 상관계수는 0.911, R2 ≥ 0.7로 유의미하게 높은 상관관계를 보였다. 상수값 결정을 위한 추가 회귀분석 결과 상관계수는 0.881, R2 ≥ 0.7로 나타났다. 상기의 결과, 개발된 예측식이 다른 도시지역의 재건축사업이나 공동주택 건설에 따른 환경영향평가나 교육환경평가의 소음·진동분야 보고서 작성 시 정합성이 높은 발파소음·진동 예측값을 도출할 수 있을것으로 기대한다.
