Design and Construction Technology of Large Dock Cofferdam Demolition Blasting

摘要：

　　This paper overviews the domestic demolition blasting technology of dock cofferdam in 10 years,including the introduction of dock cofferdam structure,the selection of blasting scheme and parameters,the identification of blasting harmful effects,especially the standards for blasting vibration control,blasting implementation technique and safety protection measures.The boatyard in this article weighted from tens of thousands to 0.5 million tons,and the cofferdam length was from dozens to hundreds of meters Blasting volume at a time was from thousands to 0.2 million cubic meters and the blasting fire dose was from several tons to 50 tons or even more.Having dozens of successful cases,we developed an entire set of design-construct and safety protection measures.
