Prediction Model for Safe Operation of Pumping Stations Optimized by the Sparrow Search Algorithm and BP Neural Network

Table 1

Classification of safety level for pumping station operation.

Level	Safe state	Description	Score
Ⅰ	Safe	Defects that do not impact the safe operation and meet safety requirements for use	100–80
Ⅱ	Basically safe	The building may be damaged but it does not affect safe use	80–60
Ⅲ	Relatively unsafe	Although the building has undergone significant damage, it can be safely used after major repairs or reinforcement maintenance	60–30
Ⅳ	Unsafe	The building is seriously damaged, and reinforcement cannot guarantee safe use	30–0
