| Abstract: | A general thinking to blasting plan for demolishing third stage roll compact concrete(RCC)cofferdams in the Three Gorges was outlined and the blasting schemes for demolition of longitudinal cofferdam and first phase and second phase transverse cofferdams were researched in detail After the comparison and analysis,the optimal blasting scheme for every section was recommended For the blasting schemes recommended,the designs of blasting parameters,firing circuit and safety protection were discussed In addition,main techno economical indexes of every recommended scheme were predicted and the research work to be required further was briefly described |
