【摘要】：針對堤壩中集中滲漏通道探測問題,基于信息熵理論和可變模糊集理論,建立用于堤壩滲漏探測的熵權(quán)-可變模糊集模型。以南方某水庫為例,首先確定各探測指標(biāo),采用客觀賦值法中的熵權(quán)法確定不同探測指標(biāo)的權(quán)重;然后計(jì)算各鉆孔水樣相對于降水、滲漏水和地下水的綜合相對隸屬度以及各個(gè)鉆孔的H值;最后依據(jù)相應(yīng)的判斷標(biāo)準(zhǔn)將鉆孔水樣進(jìn)行分類,確定鉆孔水的來源。結(jié)果表明,通過該模型確定此大壩存在4條集中滲漏通道,與前人結(jié)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.
