城市供水系统的抗震可靠度分析
|
摘要
城市供水系统在城市生命线系统中发挥着极其重要的作用。其一旦遭到破坏,将严重影响城市的正常运行秩序。因此,供水系统必须具备良好的抗震可靠性。通过计算城市供水管线的变形作为分析量。对供水系统的抗震可靠性进行了初步评定。然后,建立了城市供水系统的可靠度概率函数。最终,通过计算管线可靠度概率,将其作为分析整个城市供水系统抗震能力的依据。同时,将计算结果与城市地理信息系统结合,可以直观地从城市地形图中划分出城市供水系统的薄弱环节,并将此方法应用于实际工程中。
Urban water supply system plays a important role in the urban lifeline system. Once destroyed,urban normal operation order is seriously influenced. Therefore,the water supply system must have good seismic reliability. In this paper. Water supply pipeline deformation was taken as the amount of analysis. Seismic reliability of the water supply system was evaluated preliminary. Then,the urban water supply system reliability probability function was established. Finally,the pipeline reliability probability was calculated and taken as basis of analyzing seismic capacity of whole urban water supply system At the same time,the calculated results is combined with urban geographic information system so that,the weak links of the urban water supply system can be divided from urban relief map. The method can be used to practical engineering.
