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。
According to the traditional theory and method of earth-rock dam safety assessment model, it is difficult to fully consider the various factors that affect the safety of earth-rock dam and the problems that can not accurately evaluate the state of earth-rock dam safety. A more complete index system of earth-rock dam safety assessment is constructed, Establishing a safety assessment model of earth dam, considering all kinds of uncertainties from the same, different and anti-three aspects, get the overall safety status and development trend of the system. The engineering application shows that the model is easy to use and fast, and the analysis result is reasonable, which provides a scientific and reasonable method for the comprehensive evaluation of earth dam safety.
