摘要
在《水库大坝安全评价导则》的基础上用TOPSIS方法修正基础权重,得到最优常权,再使用均衡函数的变权公式建立模糊综合评价模型,评价混凝土坝的结构安全状况。该模型考虑了多个因素对大坝结构安全的影响,以及各种影响因素的不确定性和模糊性,同时考虑了在变权过程中指标取值的不同对评价结果的影响程度。实例表明,考虑权重随评估值变化使权重的确定更加科学合理,更客观实际地评判了大坝的结构安全性态。
Based on Guidelines on Dam Safety Evaluation, the optimal weights are got after amending fundamental weights by TOPSIS method, and then the comprehensive evaluation is modeled by varied-weight formulation in balance function to evaluate the safety condition of concrete dam. The influence factors on structure safety of dam, the uncertainty and fuzziness of each factor and the value of index during varying weights are considered in this evaluation model. Example study shows that the determination of weight is more scientific when using varying weight and the structure safety of dam can be more objectively evaluated.
