  • 简介:以便评估水分发系统的地震可靠性并且相应地做康复决定,估计管道损坏状态并且基于管子漏模型进行功能的分析是必要的。当地震发生了时,水分发系统不停地与漏服务。由与漏在管道的中心增加一个虚拟节点,压力驱动的分析的一条有效途径为模仿许多低相对情形被开发,并且一个水力的漏模型也被造与地震损坏执行水供应网络的水力的分析。然后,mean-first-order-second-moment方法被用来分析水分发系统的地震有用性。根据评价分析,被破坏或突现地在重漏被孤立并且修理的管子,它改进了水供应网络的能力并且将为提高系统的地震可靠性组成基础。水分发系统上的地震可靠性和康复决定分析的建议途径被表明通过案例研究有效。
