【摘要】：随着我国城镇化进程的加快、人们需求水平的提高,住宅建筑规模不断扩大,导致环境问题日益突出,其中,霾污染问题越来越严重,已成为当前主要环境问题。相关研究表明,建筑物在整个生命周期内排放了大量的建筑扬尘,直接或间接地增加大气中颗粒物的含量,使霾污染加重。目前,国内关于建筑扬尘排放的研究主要集中于建筑扬尘排放浓度研究、施工扬尘定量分析等方面,而关于住宅建筑生命周期内扬尘排放量的研究非常少。文章运用生命周期评价方法研究分析框剪结构住宅建筑的扬尘排放量及环境影响情况。本文基于生命周期评价理论,把框剪结构住宅建筑的全生命周期划分为四个阶段,即建材生产阶段、施工阶段、运行维护阶段、拆除及废弃物处理阶段,构建生命周期评价模型,借助SimaPro软件和Eco-indicator99环境影响评价方法,对郑州市某框剪结构住宅建筑的扬尘排放量及环境影响情况进行分析,得出全生命周期内的扬尘排放量及环境影响的模拟值,并给出最大扬尘排放量和最大环境影响的阶段及其主要影响因素;构建了框剪结构住宅建筑的扬尘排放量的理论计算模型,得出生命周期内的扬尘排放量的理论值;对比分析框剪结构住宅建筑扬尘排放量的理论值和模拟值,确定扬尘排放量最大的阶段,列出相应的解决措施,以减少框剪住宅建筑扬尘排放量和对环境的影响,为治理环境污染提供参考。
[Abstract]:With the acceleration of urbanization and the improvement of people's demand, the scale of residential buildings is expanding, which leads to more and more environmental problems. Among them, the problem of haze pollution is becoming more and more serious and has become the main environmental problem at present.Related studies show that buildings emit a large amount of building dust in the whole life cycle, which directly or indirectly increases the content of particulate matter in the atmosphere and makes the haze pollution worse.At present, the domestic research on building dust emission is mainly focused on the concentration of building dust emissions, quantitative analysis of construction dust emissions, but very little research on the residential building life cycle dust emissions.In this paper, the method of life cycle evaluation is used to study and analyze the dust emission and environmental impact of frame shear structure residential buildings.Based on the theory of life cycle evaluation, the whole life cycle of frame shear structure residential buildings is divided into four stages, that is, building materials production stage, construction stage, operation and maintenance stage, demolition stage and waste disposal stage.The life cycle assessment model is constructed. With the help of SimaPro software and Eco-indicator99 environmental impact assessment method, the dust emission and environmental impact of a frame shear structure residential building in Zhengzhou are analyzed.The simulated values of dust emissions and environmental impacts in the whole life cycle are obtained, and the stages of maximum dust emissions and maximum environmental impacts and their main influencing factors are given.In this paper, the theoretical calculation model of the dust emission amount of the frame shear structure residential building is constructed, and the theoretical value of the dust emission amount in the life cycle is obtained, and the theoretical value and the simulation value of the dust emission quantity of the frame shear structure residential building are compared and analyzed.The biggest stage of dust emission is determined and the corresponding measures are listed in order to reduce the amount of dust emission and its impact on the environment and to provide reference for the control of environmental pollution.
