PFMA在混凝土面板堆石坝安全监测优化布置中的应用

Application of PFMA in safety monitoring of concrete face rockfill dams

  • 摘要: 随着大坝风险管理理念的发展,潜在破坏模式分析(PFMA)方法得到了广泛应用。基于传统工程安全理念的大坝安全监测设计对隐患缺乏针对性,将破坏模式分析与大坝安全监测相结合可以提高监测的有效性和针对性。研究了混凝土面板堆石坝的结构特点和常见病害,应用潜在破坏模式分析方法提出了混凝土面板堆石坝的可能破坏模式,分析了各破坏模式的可监测项目及重点部位。利用破坏模式分析方法,对某混凝土面板堆石坝的监测系统提出了改进措施。研究结果表明,基于潜在破坏模式分析的大坝安全监测具有较强的针对性,可提高监测效率和可靠性。

     

    Abstract: With the development of dam risk management concept, potential failure mode analysis (PFMA) method is becoming more and more widely used. The design of dam safety monitoring based on traditional engineering safety concept lacks pertinence to hidden dangers. Combining failure mode analysis with dam safety monitoring can improve the effectiveness and pertinence of monitoring. In this research, the structural characteristics and common diseases of concrete face rockfill dam are studied, and the possible failure modes of concrete face rockfill dam are proposed by use of PFMA method, and the monitoring items and key parts under each failure mode are analyzed. Improvement measures for concrete face rockfill dam monitoring system are put forward with a view to the PFMA method. The results show that the dam safety monitoring based on the analysis of potential failure mode has strong pertinence and can improve the monitoring efficiency and reliability.
