水下工程爆破对环境影响规律研究(上)

Study on the Law of Influence of Underwater Engineering Blasting on Environment (I)

本文是长江科学院围绕三峡及长江航道整治工程水下工程爆破现场试验测试成果的汇集。依据实测数据分析了有限水域水下爆破的水击波、二次气泡脉动、爆破地震动水压力、岸坡震动及水中建筑物震动的特征和规律 ,并提出了一些看法。

The field experiments and tests achievements in underwater engineering blasting while realigning the Yangtze River channel and its Three Gorges by Yangtze River Scientific Academy are presented in this paper. On the basis of the practical data tested, the characteristics and law of water hammer wave, secondary bubbles impluse, vibration water pressure in site, bank vibration and vibration of structures in water when blasted under limited waters are analyzed, some viewpoints are put forward.
