Simulation Analysis for Concrete Gravity Dam under Penetration and Explosion

The gravity dam was taken as the researching subject, its dynamic response was simulated under EPW attack in this thesis by numerical simulation method, and the damage degree and safety problem of the dam during the attack were also analyzed. Numerical calculation referred to the dynamic and static problem simultaneously. The implicit static analysis was carried out before the dynamic calculation of penetration, and its result is one of the initial conditions in the dynamic analysis of penetration. The combined action model of penetration and explosion was built after the dynamic analysis of penetration had been finished; the problem of boundary input was also resolved in the combined calculation. The process of combined damage of penetration and explosion when EPW attacking the dam structure was simulated.
