蜀河水库蓄水后路基稳定性二次模糊综合评判

Twi-Fuzzy Comprehensive Evaluation on Roadbed Stability in the Condition of Reservoir Operation of Shuhe Hydraulic Power Plant,Hanjing River

汉江蜀河水电站属II等大(2)型水电站,水库的运行对库岸的稳定性可能造成一定的影响,甚至诱发库岸失稳灾害,这势必会影响岸坡上铁路的正常运营,所以水库运行对岸坡和铁路路基的稳定性影响必须进行分析评价。文章将影响铁路路基稳定性的因素进行总结分类,利用层次分析法确定权重,在确定各评价指标选择依据和评价标准的基础上,建立了该库岸铁路路基稳定性的二次模糊综合评判模型。

Shuhe hydraulic power plant is a large scale power plant, whose operation may impose an influence on reservoir bank stability and railway roadbed stability on both slopes of the reservoir. So we must analysis and assessreservoir bank and railway roadbed stability. The authors generalize and classify the factors affecting the roadbed stability to avoid the repetition of some indexes indexes in evaluation mode !. Twi - fuzzy comprehensive evaluation method is applied to evaluate railway roadbed stability according to the grade of its evaluation indexes.
