The Influence of Initiation Position and Depth on Anti-Explosion Safety Performance of Concrete Gravity Dam

Based on AUTODYN finite element software, this paper studies the influence of explosive equivalent and initiation depth on concrete gravity dam, analyzes the changes of internal stress, damage degree, monitoring point speed and displacement of gravity dam under different working conditions, compares the influence of underwater explosion on gravity dam under different working conditions, and provides theoretical reference for structural protection and reinforcement of gravity dam under explosive load.
