This series includes technical reports prepared by faculty, students and staff who are associated with the John A. Blume Earthquake Engineering Center at Stanford University. While the primary focus of Blume Center is earthquake engineering, many of the reports in this series encompass broader topics in structural engineering and materials, computational mechanics, geomechanics, structural health monitoring, and engineering life-cycle risk assessment. Each report includes acknowledgments of the specific sponsors for the report and underlying research. In addition to providing research support, the Blume Center provides administrative support for maintaining and disseminating the technical reports. For more information about the Blume Center and its activities, see https://blume.stanford.edu.
This report is the second of a two volume series entitled, "Preliminary Safety Evaluation of Existing Dams". The first report in the series discusses the philosophy behind the method and the probabilistic formulation for solving the ranking problem. This second report is a user manual describing the steps to perform the analysis. The user is encouraged to read Volume I to gain a complete perspective of the methodology. The preliminary safety evaluation is intended as a framework to determine a ranking of the dams in the jurisdiction of a single owner or regulator which can be used to decide the order in which dams should be studied in more detail and upgraded. The methodology to accomplish this is called a screening process. Key features of the procedure include, an estimate of the probability of dam failure, loss of life in the event of failure, recommendations and costs for upgrading a dam, and an evaluation of the cost-effectiveness of carrying out proposed remedial actions.
This manual describes each step in the procedure and provides tables and figures as aids to carry out the analysis. The methodology is presented in a way that deterministic procedures familiar to the user can be easily substituted for those suggested here. The user is encouraged to utilize methods they are most comfortable with. However, since many dam owners have not developed a program to conduct safety evaluations, simplified methods are recommended to carry out particular tasks in the analysis. A criterion for applying the screening process is consistency, to insure that a reliable, relative ranking is established.
