摘　　要：如果管线抗震可靠性已知,关于整个管网的抗震可靠性,即各点在指定烈度水平下相对于某个震害挡次仍可得到供水的概率,前人的工作只做到对节点进行估计。由于管线内点上存在着无以数计的用户或称次级管网,因此,我们必须研究抗震可靠性场分布。这样做不仅可以对父子型管网进行解耦分析,以利于实际课题在时空双向上的分割与联系,而且也可以成为分析兄弟型管网的一种技巧。前者意义自明,对于后者本文以冕宁县城给水管网为例进行分析研究。If it is known to the reliability of pipe-line anti-seismic, the anit-seismic reliability of entire pipenetwork can be got, in otherwords, the probability of supply water at every points can be obtained under the intensity level appointed relative to some earthquake-catastrophes grade. But forefathers have only done to estimate the anti-seismic reliability for every nodes. We must study the reliabilitydistrbution of anti-seismic for entire pipe-network owing to that there are tens of thousands of users at entir pipe-network or second-class pipe-network. It only can analyse for fether and son type. pipe-network and be conductive to the separation and contact of practic problem about the both time and space, but also become one technique to analyse brothers type pipe-network. The former is self-evident. For the latter, we take the water-supply pipe-network as a example and study it.
