A Case Study on Risk Assessment of Long Distance Water Supply System

AbstractDue to various influence, some potential risks were hidden in water supply system. In order to control unexpected accidents, the fuzzy comprehensive evaluation method for risk assessment is adopted in this paper. The most serious risk internal cause of water supply system is water hammer, and to eliminate the potential risks of pipe burst, water hammer was calculated under various conditions, to identify pipeline weak sections. The submerged model of was established. According to the simulation of typical case, the plan of emergency was made to deal with a series of problems caused by pipeline rupture
