摘要

Periodic dam safety assessment reviews were carried out on dams owned by Ontario Power Generation. These assessments were carried out between November 1998 to November 1999 and represented the first dam safety reviews of the dams following the initial dam safety assessments completed in 1989. The periodic reviews included standards-based assessment and Failure Modes and Effects Analyses. The Failure Modes and Effects Analyses were carried out as "Pilot Projects" to identify potential failure modes and determine the consequences of failure for various structures. An overview of the Failure Modes and Effects Analysis process is presented along with the benefits derived from the process by enhancing the standards-based approach with an increased understanding of the risks associated with the dams. Mitigating measures are also developed to reduce these risks or mitigate the consequences of failure by early detection of the development of the failure modes through enhanced monitoring and surveillance. In general, the dams are performing well.
