摘要
基于可拓学的物元模型,借助可拓评价模型对地下水封洞库岩体质量进行分类。根据岩体质量分类的影响因素,确定经典域和节域,并利用均方差法求取的权系数和引入的关联度,对地下水封洞库质量进行可拓评价。将该模型应用于黄岛地下水封洞库工程,得到了较好的预测结果,虽然与BQ法和RMR法对比得到的结果有异,但取样分析表明可拓评价模型的结果更合理,能够反映地下水封洞库岩体质量的等级。
With extensionable evaluation model,the quality of rock mass of petroleum storage cavern sealed by groundwater is classified in this paper based on Extenics Matter-Element model.According to the influencing factors of rock mass quality classification,the classical field and segment field are determined.Meanwhile,by means of weight coefficients obtained by mean square deviation and the introduced correlation degree,an extensible evaluation model is made for the rock mass quality.This model is applied in the Huangdao cavern sealed by groundwater,and good prediction result has been obtained.By sampling analysis,it shows that even though the result differs somewhat from that of BQ method and RMR method,this model is more reasonable,and is capable of reflecting the grade of rock mass quality.
