| Abstract: | Earthquake damage of water supply unit is predicted on the basis of analyzing the pipeline seismic performance function and the limitation state equation. Based on Monte Carlo method and neural network, the running state and the destroy state of each pipeline are simulated. And the reliability of the water supply network connectivity is analyzed by combining with graph theory. The feasibility of this method is verified through a case study. |

| Keywords: | water supply network neural network Monte Carlo graph theory connectivity reliability |
