Abstract

Abstract

Numerical simulation has been carried out for blasting demolition of rolling compact concrete cofferdam in crosswise direction of which belongs to the third term of the Three-gorge project using dynamic finite element program LS-DYNA. The influence of corridor and reservoir water on blasting-demolition effect has been numerically analysed. The calculated resultes show that corridor and reservoir water influence forming and extent of blasting notch heavily,which must be considered sufficiently during blasting practice.
