| 摘 要： | 基于可拓工程方法,在物元模型理论的基础上建立了洞室岩体质量评价的物元模型,提出采用层次分析法计算物元模型中各评价指标的权系数的方法。通过实际洞室岩体质量等级的关联度计算,对水布垭水电站地下厂房的围岩岩体质量进行了评价,得出与现场实际相符合的结论。研究结果表明:层次分析法用于确定洞室岩体质量评价指标的权系数是可行的,并且洞室岩体质量的可拓学评价能够较好地反映洞室岩体的质量等级,具有较好的适用性。

| Abstract: | The matter element model of cavern rock quality evaluation is established using matter element model theory based on extension engineering method.The stratification analysis method used to calculate weight aggregation of evaluating factors is proposed.Through calculating the relational degree of the actual cavern rock quality grades,the rock quality of Shuibuya Waterpower Station cavern is evaluated by extenics,and the conclusion has good relation with the facts.It is shown that stratification analysis method is feasible to calculate the weight aggregation of evaluating factors.The extenics evaluation of cavern rock quality with high applicability can more precisely reflect the quality classification of the cavern rock. |
