Failure process analysis on overload of arch dam

摘要

Arch dam's failure is a super nonlinear irreversible process. We can find the damage mechanism from research of it and get a more reasonable and perceive safety factor. It analyses overload of the highest RCC arch dam of the world and shows dam's failure process by water specific gravity overcharge method and water-level overcharge method. It gets overload safety factor from study on arch dam's failure process and also gives the reason that why different methods get different safey factor.
