Abstract

To explore the related problems of the reliability of cold-wave resistance connectivity of underground-based municipal water supply network, this paper, taking a city’s water supply network as an example, mainly utilizes the First Order Second Moment method (FOSM) to calculate the reliability with the change of temperature. Based on this, it is concluded that the reliability of the water supply network is related to the temperature during the cold-wave period. When the temperature is different, the reliability of the water supply network is also different. Therefore, when designing the water supply network, the influence of the cold wave should be taken into account, and the freeze stress of the network should also be taken into account when analyzing the reliability of the water supply network during the cold-wave period.
