Abstract The main result s of blasting experiment on concrete cover layer of overfall2dam in the reservoir are int ro2
duced. On the basis of experiment data and st ress wave theory , the computation formula of damage depth is de2
duced. It is concluded that the blasting st ripping way is completely capable to satisfy the demand of design and con2
st ruction under the condition of adding soft cushion.
