摘　　要：城市轨道交通规划建设一般都在大中型城市的建成区,常常伴随大面积的房屋拆除和城市更新改造,加上项目本身涉及的临时建构筑物的拆除,会产生大量的建筑废弃物。2020年我国城市建筑垃圾产生量预计突破30亿t,资源化处理率约13%,减少建筑垃圾排放,提高资源化利用率已刻不容缓。深圳市黄木岗立交拆除项目通过资源化利用减少资源浪费,实现“变废为宝”。The planning and construction of urban rail transit are generally in the built-up areas of large and medium-sized cities,often accompanied by large-scale house demolition and urban renewal.At the same time,the project will demolish the temporary buildings.Both of them will produce a lot of construction waste.In 2020,the output of urban construction waste in China is expected to exceed 3 billion tons,and the resource utilization rate is about 13%.It is urgent to reduce the emission of construction waste and improve the resource utilization rate.Huangmugang overpass demolition project in Shenzhen reduces waste of resources through resource utilization and realizes“turning waste into treasure”.
