摘要
针对传统的土石坝安全评估模型理论和方法难以全面考虑影响土石坝安全的多种因素及不能准确评价土石坝安全状态的问题,构建了更完善的土石坝安全评估指标体系,利用集对分析理论建立土石坝安全评估模型,从同、异、反三个方面考虑各种不确定性,得到系统整体的安全状况和发展趋势。工程应用表明,该模型使用方便、快捷,分析结果合理,为综合评价土石坝安全提供了科学合理的方法。
The traditional model and theory of dam safety assessment is difficult to consider the uncertainties fully on the dam safety status, and it can not give an accurate evaluation. The more comprehensive evaluation index system of dam safety is build and the dam safety assessment model is established based on the set pair theory. The safety status and de- velopment trend are obtained from the aspect of homology, difference and opposition by considering the uncertainty. En- gineering applications show that the model is easy to use, and the results are reasonable. Therefore, it provides a scientif- ic and reasonable method for comprehensive evaluation of earth-rockfill dam safety.
