摘要
随着抽水蓄能电站的不断发展,电站安全问题逐渐突出,针对某抽水蓄能电站下库区混凝土重力坝的安全状况进行安全评价分析。下库重力坝的安全评价问题,本质上是一个多因素影响问题。结合工程相关资料,筛选出评价指标,构建适用于抽水蓄能电站下坝址重力坝的安全评价体系,结合区间数理论及可拓物元思想,提出基于改进AHP的可拓物元云模型评价方法。选取某实际工程验证评价模型的有效性,结果表明,评价结果与大坝实际运行状况基本一致,研究结果可为大坝渗流安全评价提供参考。
With the continuous development of pumped storage power station,the safety problem of power station is becoming more and more prominent.This paper makes safety evaluation and analysis for the concrete gravity dam in the lower reservoir area of a pumped storage power station.The safety evaluation of the lower reservoir gravity dam is essentially a multi-factor problem.Based on the engineering data,the evaluation index is selected,and the safety evaluation system suitable for the gravity dam at the lower dam site of pumped storage power station is constructed.Combining the interval number theory and the extension matter-element idea,an evaluation method of extension matter-element cloud model based on improved AHP is proposed.A practical project is selected to verify the effectiveness of the evaluation model.The results show that the evaluation results are basically consistent with the actual operation of the dam,and the research results can provide reference for dam seepage safety evaluation.
