Abstract

In order to evaluate reliability of post⁃earthquake water supply network，earthquake disaster was simulated by using Monte Carlo method，and hydraulic analysis of pipe network was conducted by pressure⁃driven distribution method. Then，surplus power entropy of the network was calculated from which statistical curve of surplus power entropy data of nodes and pipe networks，comparison of flow entropy and surplus power entropy，and surplus power entropy distribution of different intensities were obtained. Finally，factors that influenced surplus power entropy were studied building on data analysis. The results show that surplus power entropy of network nodes based on Monte Carlo simulation is basically stable after 3 000 simulations，and its value depends on water supply path from source points to nodes and distribution uniformity of surplus power factors in different paths. © 2020 China Safety Science Journal.
