발파 진동레벨을 이용한 내륙 양식장내 수중소음 추정에 관한 연구

Abstract

With the rapid growth of the industrial economy and a growth-oriented economic policy, demands for development of national territory have been increasing annually. In particular, as diverse construction projects such as road construction, tunnel excavation, subway construction in metropolitan cities, and reconstruction of old buildings have been very active, we have suffered from environmental problems such as noise, vibration, fly rock and dust. Some of the recent articles show that there are methods to predict underwater noise through correlations based on measurement data of blast vibrations and underwater noise using a speed meter collected from test blasting. However, it was reported that there were empirical cases when underwater noise was predicted with the use of an acceleration-based level meter, but there were no relations to estimate blast vibration levels obtained through actual measurements related to underwater noise. This study aimed to develop a base for having fewer disputes by correlating blast vibration level with underwater noise using a vibration level meter when there is a blast near fish farms in the situation where we have no underwater sound measurement equipment or measurements can not be made at farms because of other reasons.
