| 中文摘要 | 为探索环境友好型建筑结构材料,运用生命周期评价方法,结合实地调研,得到了规格材、胶合木和定向刨花板3种木结构产品物化阶段的环境影响。研究表明,在单位体积3种木结构产品的物化环境影响负荷和不可更新资源消耗中,定向刨花板最大,胶合木其次,规格材最小。进而分析了规格材梁、胶合木梁和工字搁栅3种受弯构件的环境影响状况,结果表明,工字搁栅的材料使用效率最高,环境影响最小,其次是胶合木梁和规格材梁。该结果可作为包含木结构产品的建筑工程环境影响评价的基础数据。; To find environmental friendly construction material,the embodied environmental profiles of timber,glulam,and oriented strand board(OSB) were analyzed using the life cycle assessment method and industry investigation.The results show that OSB has the most embodied environmental burden and the largest consumption of non-renewable resources,while glulam has less and timber has the least per cubic meter.The environmental impacts of three kinds of bending members(sawn timber beam,glulam beam,I-joist) were also evaluated and compared.The results show that timber beams have the most embodied environmental burden while glulam beams have less,and I-joists have the least.Thus,material is best used in I-joists.These results provide basic data to assess the life cycle environmental impact of construction projects using wood products. |
