| Abstract: | A hydraulic analysis program of the water supply system in earthquakes is introduced based upon the hydraulic analysis method in a normal state.On the basis of the seismic response analysis of buried pipelines,a new leakage model is presented in this article.This model is applied to the analysis of the water supply system with the first-order reliability method(FORM),a new analysis method of the capability reliability of a water supply system is suggested.This method is applied to the seismic hydraulic analysis of Shenyang water supply system,which consists of 463 nodes and 767 pipelines.A satisfied solution of the capacity reliability of the water supply system can be gained by suggested algorithm within an acceptable time. |
| Keywords: | water supply system leakage model capacity reliability |
