广州地区建筑可再循环利用材料用量比例研究

Study on the Proportion of the Recyclable Building Materials in Guangzhou

基于调查统计的128个工程项目的建筑材料用量,计算分析出建筑工程在不同功能、不同结构、不同层数等工况下,可循环材料用量比例的分布值域及变化规律。研究结果表明:建筑结构类型和建筑材料选用是可循环材料用量比例的重要影响因素;不同功能类型建筑的可循环材料用量比例分布区间是2.93%~12.01%,不同结构类型建筑的可循环材料用量比例分布区间是5.13%~46.60%,不同层数建筑的可循环材料用量比例分布区间是5.81%~14.00%。

Based on the survey of the consumption of recyclable building materials in 128 projects, the distribution range and variation principles of the proportion of the recyclable materials are calculated and analyzed from the as- pects of different functions, different structures and different floors of the building. The statistical results show that the types of building structures and selection of building materials are important factors in the proportion of recy- clable materials. The recyclable materials proportion in the buildings with different functions ranges from 2.93% to 12.01%, while that in the building with different structure is about 5.13% - 46.60%. Conversely, the total amount of the floors has slight effects as the recyclable materials proportion fluctuates in much smaller range as 5.81% to 14.00%.
