- Abstract
This study aims to explore the causes of sudden water pollution accidents in the main canal of the South-to-North Water Diversion Project in China. Triangular fuzzy function and fault tree analysis method were combined, and qualitative and quantitative fuzzy fault tree analyses of sudden water pollution accidents in main canals of the South-to-North Water Diversion Project in China were conducted. Results show that the probability of sudden water pollution accident in the main canal of the South-to-North Water Diversion Project is 0.0205%, which is in accordance with the actual situation. The instantaneous deterioration of water quality, excessive water quality, artificial poisoning, and terrorist attacks have the greatest impacts on sudden water pollution accidents, followed by vessel traffic accidents and geological hazards, and finally by road traffic accidents. The conclusion provides a decision-making reference for the prevention and treatment of sudden water pollution accidents in the main canal of the South-to-North Water Transfer Project.
