摘要(Abstract)：
佐敦谷场地开挖及平整工程是香港有史以来在市区内进行的最大规模爆破工程。根据在毗邻高层居民楼进行的爆破工程产生的空气冲击波超压监测获得的大量数据,对影响爆破空气冲击波超压的因素及其控制方法进行了分析研究。文章建议对在市区内进行的爆破工程采用134dBL和120dBA两个指标,对爆破空气冲击波超压有可能造成的结构破坏和爆破噪声进行限制。
The project of "Site Formation and Associated Infrastructure Works at Jordan Valley" is the largest urban blasting project in the history of Hong Kong.Based on collected data of air overpressure(AOP)produced by blasting which was performed near a high residential buildings in the urban area,the factors affecting AOP and control methods were studied in this paper.A recommendation of using dual standards,120dBA and 134dBL,was suggested as the limitation of controlling blasting noise and possible damage caused by blasting AOP in conducting blasting engineering in urban area.
