提出了城市煤气管网系统震害的一种预测方法,该方法可以考虑地震作用等的随机性。用概率方法给出了煤气管线不同破坏状态的概率值,并可对整个管网系统的抗震可靠性进行概率性震害预测.
A prediction method of urban gas pipeline network system damage is proposed, which can consider the randomness of earthquake action and so on. Probability method is used to give the probability value of different damage states of gas pipeline and to predict the earthquake damage reliability of the whole pipe network system.
