The Protection Against and Controlling to The Influences of Shock Wave Caused by Underwater Blasting

摘要

The measurement results of blasting to dismantle the cofferdam of tail outlets 1~# and 2~# of Dachaoshan hydroelectric power station on Yunnan and the in-situ experiment made upon water shock wave have been described in the paper. By way of comparative analysis, the decreasing effect of the air bubble curtain to the water shock wave was quantitatively obtained, and the acting manner and characteristics of the dynamic hydraulic pressure and water shock wave created by underwater blasting with various methods and different explosive charge were analysed.
