| Abstract: | Reliability theory of structures was carried out in the beginning of the existing storm sewer system node.And the influence of the uncertain factors were analyzed,which included node water carrying capacity of upstream and downstream pipe diameter d,roughness n,hydraulic gradient J,the calculating model NR of and the water flow q that flowed into the nodes.Monte-Carlo method was utilized to define the node reliability,and finally to identify the reliability of existing network in a way of the narrow bound method under a tandem structure model. |

| Keywords: | existing storm water pipe network uncertainty Monte-Carlo method narrow limits law reliability |
