摘　　要：针对岩溶帷幕灌浆效果评价存在控制因素多、难以统筹定量分析、现行方法具有片面性等问题,提出了基于模糊综合评价法的灌浆效果评价模型。首先构建了模型因素集U、评价集V、评价矩阵R,然后确定了基于层次分析法的权系数向量D,通过模糊合成算子得到了决策集E,实现了灌浆效果多维度定量评价。并以构皮滩水电站为例对模型进行了验证分析,分析结果表明:提出的灌浆效果评价模型与现行传统评价方法具有较好的同步性,但相较于现行方法,该模型不仅可反馈灌后岩体透水率,也可诠释灌后岩体完整性和岩溶封堵程度,具有更高的评价维度和更全面真实的评价体系,具有广阔的行业推广前景。Aiming at the problems of many control factors,difficulty in overall quantitative analysis,and one-sidedness of current method in the evaluation of karst curtain grouting,this paper proposed a grouting effect evaluation model based on fuzzy comprehensive evaluation method.Firstly constructing a model factor set U,an evaluation set V,and an evaluation matrix R.Then the weight coefficient vector D based on AHP was determined,the decision set E was obtained through the fuzzy synthesis operator,and the multi-dimensional quantitative evaluation of the grouting effect was realized.The model was verified and analyzed by Goupitan Hydropower Station.It showed that the evaluation model of grouting effect proposed in this paper had good synchronization with the current method.Compared with current the method,the proposed model can not only feeds back the water permeability of the rock mass after grouting,but also interpret the integrity of rock mass and the sealing degree of karst after grouting.This model has a higher evaluation dimensions and more comprehensive and real evaluation system,and has broad prospects for industrial promotion.
