| 摘 要： | 本文将大范围边坡稳定性的众多影响因素进行总结分类,并针对评价指标分级的特点,将传统的两级模糊综合评判模型作适当改进,进行二次模糊综合评判.以某水电站近坝库岸边坡为例,在确定各评价指标选择依据和评价标准的基础上,建立了该库岸边坡稳定性的二次模糊综合评判模型.结果表明,基本地质因素在模糊综合评判中起着控制作用,其中岸坡结构类型和岩性对库岸边坡稳定性的影响最为显著.

| Abstract: | More factors in slope stability quantitative assessment often result to repetition of some factors, thus it is important to optimize the factors for evaluation. The authors generalize and classify the factors affecting the large-scale slope stability to avoid the repetition of some indexes in evaluation model. Based on some improvements on the classic two-grade fuzzy comprehensive evaluation model, twi-fuzzy comprehensive evaluation method is applied to evaluate the large-scale slope stability of a hydroelectric station according to the grade of its evaluation indexes. This model takes account of the effect of influencing factors and it is proved that twi-fuzzy comprehensive evaluation model is practical and reliable. The result indicates that the most important factors influencing the slope stability are basic geological factors, among which slope-type and lithology are the more important factors influencing bank slope stability than others. |
