In order to reduce the impact of the blasting operation in the stilling pool to the dam body,the blasting wave is combined with the principle of cavity expansion,and a non-stationary dynamic calculation method is used to simulate the dynamic response of the dam structure within a certain range.Through simulation calculations of the response of high dams under explosive shock waves,four parts of high dams that are prone to stress concentration under explosive shock waves were identified.Through the analysis of experimental results,it has been verified that explosions have no impact on the safety of the dam body.
