【摘要】：针对堤坝中集中渗漏通道探测问题,基于信息熵理论和可变模糊集理论,建立用于堤坝渗漏探测的熵权-可变模糊集模型。以南方某水库为例,首先确定各探测指标,采用客观赋值法中的熵权法确定不同探测指标的权重;然后计算各钻孔水样相对于降水、渗漏水和地下水的综合相对隶属度以及各个钻孔的H值;最后依据相应的判断标准将钻孔水样进行分类,确定钻孔水的来源。结果表明,通过该模型确定此大坝存在4条集中渗漏通道,与前人结果一致。
[Abstract]:Based on the information entropy theory and the variable fuzzy set theory, an entropy weighted variable fuzzy set model is established for the detection of the concentrated leakage channel in the embankment, which is based on the information entropy theory and the variable fuzzy set theory. Taking a reservoir in the south of China as an example, each detection index is determined at first, and the weight of different detection indexes is determined by entropy weight method in objective assignment method. Then, the comprehensive relative membership degree of each borehole water sample relative to precipitation, leakage water and groundwater and the H value of each borehole are calculated. Finally, the borehole water sample is classified according to the corresponding judgment standard, and the source of borehole water is determined. The results show that there are 4 concentrated seepage channels in the dam by the model, which is consistent with the previous results.
