Safety Risk Evaluation of Pumping Stations Based on Catastrophe Progression Method
The safe operation of the pumping station plays a vital role in the operational efficiency of the South-to-North Water Diversion Project.In order to evaluate the safety risk of pumping station operation more scientifically and objectively,this paper combines the actual operation of the pumping station project on the east line of the South-to-North Water Diversion Project,Firstly,the Delphi method is used to classify the safety risk,and then the risk factors are normalised to construct the South-to-North Water Diversion pumping station operation safety risk evaluation indicator system.Finally,a large pumping station on the east line of the South-to-North Water Diversion is taken as an example,and the operation risk of the pumping station on the east line is evaluated by using the mutation level method.The results show that the overall safety operation risk level of this pumping station is acceptable.The operation management system is not sound but belongs to the negligible level;the operation management behaviour is not standardized;the safety condition of metal structure and the safety condition of electromechanical equipment are bad belonging to the acceptable level;the safety condition of civil structure is bad,but belongs to the general level.
