Cascade hydropower hub group dam continuous bursting risk analysis method and system

The invention discloses a cascade hydroelectric hub group dam continuous bursting risk analysis method and a cascade hydroelectric hub group dam continuous bursting risk analysis system. The analysis method comprises the following steps: constructing a dam continuous burst physical model of the cascade hydropower hub group, and a feed dam flood flow calculation and feed dam occurrence condition judgment model of the dam continuous burst physical model, and on the basis of the above models, according to data such as dam body materials, reservoir capacities, dam heights and dam crest elevations of all dams in the hydropower hub group, calculating the feed dam occurrence condition of the dam continuous burst physical model; and calculating and determining whether dam break or overtopping occurs in each dam and the flood routing condition after dam break or overtopping occurs. The method is wide in application range, does not need to collect excessive basic data, is high in calculation efficiency and accuracy, an
