Study On The Evaluation Of Water Supply Network Vulnerability

City water supply system is composed by many parts, from the source of water to the water faucet of user's, any damage of these parts will lead to somewhat influence to water quantity, hydraulic pressure or water quality, at the same time, most water quality detection is periodical and afterwards. We must analyze the possible problems, infections and probability of any parts for water supply system, to take measures, and make the risk lowest. At present, the research of this field is little, the evaluation on the security hidden trouble and weakness teaches of whole water supply system is not particularity or complete, many regions have not start the evaluation on this aspect, so, it is imperative under the situation to estimate the vulnerability of water supply network.The thesis analyzed and researched relate data of vulnerability evaluation on many fields, then, analyze the vulnerability of water supply network, and strike up the vulnerability evaluation index system of water supply network. Adopted layered analysis system, using vulnerability analysis function of water node to estimate the index value of the water node. Get the vulnerability grade of water supply network through index value of the water node. At last, applied vulnerability theory and risk evaluation measures of water supply network to the material projects of vulnerability analysis and risk evaluation of water supply network.
