【摘要】：隨著中國城鎮(zhèn)化建設(shè)進程的加快,建筑垃圾的產(chǎn)量將越來越多,再生混凝土的應(yīng)用不僅能夠解決建筑廢棄物日益增多的難題,而且可以節(jié)約大量的砂石資源。為了對混凝土再生粗骨料質(zhì)量進行排序和優(yōu)選,基于信息熵—未確知測度理論構(gòu)建了混凝土再生粗骨料質(zhì)量評價模型。根據(jù)《混凝土用再生骨料標(biāo)準(zhǔn)》確定評價指標(biāo)體系和單指標(biāo)測度函數(shù);利用信息熵理論確定各指標(biāo)的權(quán)重,依據(jù)各個指標(biāo)的樣本實測結(jié)果計算單指標(biāo)測度評價矩陣和多指標(biāo)測度評價向量;按照置信度識別準(zhǔn)則進行質(zhì)量等級評判并應(yīng)用實例分析檢驗該方法的有效性。結(jié)果表明,信息熵未確知測度理論不僅可以對單個樣本進行質(zhì)量等級評價,還對評價結(jié)果處于同一級別內(nèi)的樣本質(zhì)量的好壞進行排序。
[Abstract]:With the acceleration of urbanization construction in China the output of construction waste will be more and more. The application of recycled concrete can not only solve the problem of increasing construction waste but also save a lot of sand and stone resources. In order to sort and select the quality of recycled coarse aggregate of concrete, based on the theory of information entropy and unascertained measure, a model for evaluating the quality of recycled coarse aggregate of concrete was established. According to the Standard of recycled aggregate for concrete, the evaluation index system and single index measure function are determined, and the weight of each index is determined by using the information entropy theory. The single index measure evaluation matrix and multi-index measure evaluation vector are calculated according to the measured results of each index, and the quality grade is evaluated according to the confidence recognition criterion and the validity of the method is verified by an example analysis. The results show that the information entropy unascertained measure theory can not only evaluate the quality grade of a single sample, but also rank the quality of a sample with the same level of evaluation results.
