摘　　要：城市建筑垃圾不断增多,而建筑垃圾通过合理利用可以减少对人类和生态环境的影响。针对房屋拆迁后产生的建筑垃圾,依托西安外环高速公路建筑垃圾回填路基项目分析其组分。为发挥其路用性能,通过开展室内土工试验、筛分试验、击实试验及CBR试验,分析得到建筑垃圾的级配曲线及击实曲线等基本物理力学参数。通过对比路基工程的压实标准,评价其用作公路工程回填填料的可行性。Urban construction waste continues to increase,and reasonable utilization of construction waste can reduce the impact on human beings and the ecological environment.Aiming at the construction waste generated after house demolition,the components are analyzed based on the construction waste backfill roadbed project of Xi’an outer ring expressway.In order to give full play to its road performance,basic physical and mechanical parameters such as the gradation curve and compaction curve of construction waste are obtained by conducting indoor geotechnical tests,screening tests,compaction tests and CBR tests.By comparing the compaction standards of roadbed engineering,the feasibility of using it as backfill for road engineering is evaluated.
