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

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.
