摘  要:
The changes of the nodes pressure under abnormal conditions are analyzed and the trend-surface analysis model for water-supply pipe network is established in this paper.Through contrasting trend chart and the diversity chart under the conditions of normal and abnormal pipe network pressure,the degree and the general scope of the pipeline leakage can be determined.Meanwhile,the water-supply network of certain city is analyzed as an example.
