Research on Safety Evaluation of Water Supply Network Based on Urban Physical Examination

The current urban physical examination work gradually developed into a normal, safe operation of water supply network has been one of the important indicators of urban physical examination. In order to explore the perfection of water supply network indexes related to urban physical examination and how to carry out safety assessment of pipeline network, the current situation of water supply network and the evaluation indexes of water supply network in urban physical examination are introduced. Give examples of the use of semi-quantitative evaluation method, quantitative evaluation method and big data analysis method. According to the research status, the shortcomings and difficulties in the safety assessment of water supply network are put forward.
