摘　　要：本文开展了水电厂压力钢管运行安全监测及预警系统关键技术研究,提出了表征压力钢管运行状态的特征参数并制定了各监测参数的预警规则,以及基于D-S证据理论的压力钢管运行评价体系,将压力钢管运行状态评价为险情、异常、正常三种状态。通过该系统,电厂管理部门可以更加合理的制定检修计划,避免资金的盲目投入,实现防灾、减灾目标。The key technology of the operational monitoring and pre-alarm technique for hydropower plant pressure pipe is researched in this paper. The running characteristic parameters of the pressure pipe is proposed,the alarm rules for those parameters is formulated and the pressure pipe evaluation system based on D- S evidence theory is proposed,which can evaluate pressure pipe running status as dangerous,abnormal,normal states. Through this system,the plant management can make a more reasonable maintenance plan,to avoid blind investment and achieve disaster prevention and mitigation targets.
