摘要
针对当前建筑垃圾资源化利用模式的不完善、不完整及数据信息不完备等问题,建立建筑垃圾资源化利用评价模型至关重要。在构建的建筑垃圾资源化利用评价指标体系的基础上,采用粗糙集理论确定相应的指标权值,通过可拓综合评价法对西安市内现存的具有代表性的10种建筑垃圾资源化利用模式进行等级评价,得出结论:建筑垃圾资源化是城市可持续发展的必然趋势,其中,现场破碎与集中处理相结合、再生砌块与路基回填综合利用的模式效益最佳。
In view of imperfection,incompleteness and incomplete data information in the current construction and demolition waste（ C ＆D waste） utilization model,it is important to establish the assessment of C＆ D waste utilization models. Based on the evaluation index system of the utilization model of C ＆D waste,rough set theory is used to determine the corresponding index weight,and the existing ten kinds of typical C ＆D waste utilization models in Xi＇an are ranked by the extension comprehensive evaluation method. It is concluded that the C ＆D waste utilizing road is the inevitable trend of urban sustainable development and the method that is combined on-site fragmentation with off-site fabrication,recycled blocks making with subgrade backfill utilization of C＆ D waste will be the most profitable one.
