Abstract: To adapt to environmental changes and safety needs, the design specifications related to dam safety evaluation are constantly being revised and improved. Safety evaluation is an important measure for dam safety management. The revision and update of the specification will inevitably lead to some changes in methods and parameters. Therefore, in the safety evaluation of earth-rockfill dams, there are some differences between the review calculation results and the original design. This paper discusses
the main differences in discharge capacity review, seepage stability review and seismic stability review, to improve the safety evaluation of earth-rockfill dams.

Key words: safety evaluation, earth-rockfill dams, update of the specification, review calculation

摘要： 为了适应环境变化和安全需要，大坝安全评价相关的设计规范不断修订完善。安全鉴定是大坝安全管理的重要措施，规范的修订更新必然会有一些方法和参数的变化，因此在土石坝安全鉴定工作中，复核计算与原设计结果存在一些差异。针对主要存在差异的泄流能力复核、渗流稳定复核和抗震稳定复核等方面进行探讨，力求起到参考作用。
