摘　　要：为解决建筑废料造成的环境污染和建筑资源短缺问题,设计一种基于信息熵的建筑废料可再生循环利用效果评估模型.通过深入分析信息熵基本概念,创建基于信息熵的模糊评估模型,将废料处理效果、工期、总成本费用、投资效益、社会效益以及风险因素作为一级评估指标,构建建筑废料可再生循环利用效果评估指标体系,调用创建的模糊评估模型,实现四种不同建筑废料处理模式的建筑废料可再生循环利用效果评估.实验结果表明:现场破碎集中外运和再生砌块与路基回填处理模式的建筑废料可再生循环利用效果最理想;利用所得评估结果处理建筑废料,可显著降低各类污染物总排放量,并且能够大幅度提升各类建筑废料可再生利用率,最高值可达到85%左右.To solve the problems of environmental pollution and shortage of construction resources caused by construction waste,an evaluation model of renewable recycling effect of construction waste based on infor-mation entropy is designed in this paper.Through in-depth analysis of the basic concept of information entro-py,a fuzzy evaluation model based on information entropy is established.The waste treatment effect,con-struction period,total cost,investment benefit,social benefit and risk factors are taken as the primary evalu-ation indexes.The evaluation index system of the effect of renewable recycling of construction waste is con-structed,and the created fuzzy evaluation model is invoked to realize the effect evaluation of renewable recy-cling of construction waste in four different construction waste treatment modes.The experimental results show that the recycling effect of construction waste is the best in the mode of on-site crushing,centralized outward transportation and recycled block and subgrade backfilling.Using the evaluation results to treat con-struction waste can significantly reduce the total emission of various pollutants and greatly improve the renew-able utilization rate of various construction waste,with the maximum value of about 85%.
