Using GIS to analysis urban water supply pipeline network characteristic, it can make full use of GIS spatial data management and graphics processing advantages. This paper is on the basis of clarified the importance of the dynamic characteristics, it include three aspects of research. First, topological graph modeling, establishes the section between the nodes and directed graph, and uses adjacency list to store; Second, spatial database structure, it designed by the topography and galleries, some data sets, the line data set, the surface data and document data sets of pipe network GIS spatial data structure; Third, nodal flow dynamic characteristics, analysis of node flow of small changes ,which can lead to node pressure and the change in the flow section, and build the mathematical model. In this paper, the research contents to ensure the security of urban water supply, improve the level of urban management information, improve emergency management capability of urban is of great significance.

Stochastic Interpolation

Historical seismic events show that water supply networks are increasingly vulnerable to seismic damage, especially in a violent earthquake, which leads to an unprecedented level of risk. Evaluation of vulnerability to seismic hazards can be considered as one of the first steps of risk management and mitigation. This paper presents a stochastic interpolation-based fractal model for assessing the physical vulnerability of urban water supply pipelines. Firstly, based on the formation mechanism of natural disaster risk and the concept of seismic vulnerability, the most representative factors were selected as the vulnerability evaluation indices, and the classification criterion of each index was teased out according to the earthquake damage investigations and researches on the aseismatic behavior of water supply pipelines. Secondly, considering the randomness of vulnerability to earthquake hazards, the test data set was produced by way of stochastic interpolation according to the uniform distribution, on the basis of the classification criterion. The fractal dimensions of all of the indices were calculated based on the test data set. The fractal interpolation diagnosis function for identifying the vulnerability levels of pipelines to earthquake disasters was established. Finally, the application of the proposed model to a real water supply network and its comparative analysis showed that the water supply network was basically in a medium vulnerability level. Through the case study verification, we could find that the model was theoretically and practically feasible. This study helps to gain a better understanding of the extents of potential vulnerability levels of water supply pipelines. It can provide technical support for disaster prevention plans of urban water supply networks.
