Purpose: This study aims to prevent disasters such as structural damage and collapse caused by blasting and impact noise by addressing overall problems related to vibration velocity measuring devices, measurement standards (measurement methods), and the conversion formula between vibration level and vibration velocity during blasting operations. Method: The study involved comparative analysis of measurements taken at construction sites, examination of current laws and institutional systems, and verification of conversion formulas between vibration level and vibration velocity. Based on this, problems were identified and corresponding improvements were proposed. Result: There are currently no statutory regulatory standards for vibration velocity, nor formal approval (type approval) for manufacturing or importing vibration measuring devices, or established measurement standards. Significant discrepancies were observed in the measurement results obtained from five different domestic and international measuring devices. Furthermore, substantial differences were found among the various conversion formulas, which leads to major problems when these measurements are used for blasting design or dispute resolution. Accordingly, improvement measures were proposed to address these issues. Conclusion: It is expected that establishing government-level regulatory standards for vibration velocity, implementing type approval and accuracy tests for vibration measuring devices, enacting legal measurement standards for vibration velocity, and standardizing the conversion formula between vibration level and vibration velocity will help resolve disputes and prevent disasters such as damage to buildings or structural collapse.

연구목적: 발파 시 측정하는 진동속도의 측정기기, 측정기준(측정방법), 진동레벨-진동속도 환산에 대 한 전반적인 문제 를 해결하여 발파 및 충격음에 의한 건축물 피해 및 구조물 붕괴 등의 재난을 예방한 다. 연구방법: 현행 법규 및 제도의 조사, 공사장별 측정 및 결과 비교, 진동레벨-진동속도 환산식 검증 등의 연구를 통해 도출된 문제점과 개선방안을 제시코자 한다. 연구결과: 진동속도는 법적 규제기준과 제작· 수입시 성능 등의 형식승인 및 측정기준 등이 없고, 국내외 5종의 측정기로 측정 결과는 큰 편차가 있었고, 환산식별로 차이가 심해 발파설계 및 분쟁 활용 시 문제가 커서 개선대책을 제시하였다. 결론: 정부차원의 진동속도 규제기준 마련, 진동속도 측정기의 형식승인 및 정도검사 실시, 진동속도 측정기 준 법제화, 진동레벨-진동속도 환산식 표준화 등이 마련되면 분쟁 해소와 건축물 피해나 구조물 붕괴 등의 재난 발생 예방 효과가 있을 것으로 기대된다.
