【摘要】：碳排放是全球性的热门话题,如何实现"低能耗,高效率"的社会、经济发展方式是任何一个国家所追求的目标。我国自"十二五"期间开始逐步落实"京都议定书"的减排目标后,取得了一定的成效,但我国粗放型的传统增长方式仍然长期存在。因此我国政府仍把低碳发展作为"十三五"的重要规划。鉴于此,本文通过对我国冲孔灌注桩施工过程碳排放的研究,从细节着手,力求探索出节能减排的方案,促进工艺的优化与调整,从长远上确保我国建筑行业的绿色可持续发展。建筑物基础部分工程量约占整个建筑物工程量的四分之一,潜在节能空间达到5%-10%,可见对建筑物基础部分施工的研究意义较大。通过对冲击式钻孔灌注桩施工碳排放的研究,可以获得类似施工工艺的碳排放情况,可以有效地指导施工工艺与施工方法的完善。本文首先对冲孔灌注桩施工工艺进行分析,结合其特定环境、人工、材料、机械等特点,得出该工艺碳排放因子,同时确定成桩单位工程量所需要的因子用量。以碳排放计算国标为支撑,生成冲孔灌注桩基础施工阶段的碳排模型。结合工程实践经验与人、材料、机械的消耗量,在特定环境下获取冲孔工艺下的碳排放因子。基于《建筑碳排放计量标准》下的"清单统计法"与"建筑信息模型法"得出碳排放量,获得延平区冲孔灌注桩施工碳排放的指标约在90.67kgC02/m3上下浮动;施工机具的碳排放量达到基础施工碳排放量的75.24%,.其中冲孔机的碳排放量达到基础施工碳排放量的一半以上。最后基于冲孔灌注桩施工工艺下的碳排放数据,以TOSIS法与模糊综合评价法为研究手段,编制模型,将模型进行方案比选与评价,得出基于冲孔灌注桩施工工艺下的节能减排目标与措施。以微观实践着手,对建筑行业的绿色发展贡献一定的力量。
[Abstract]:Carbon emissions is a hot topic, how to achieve "low energy consumption, high efficiency" of the society, the mode of economic development is a national goal. Since China's "12th Five-Year" period began to gradually implement the "Kyoto Protocol" emission reduction targets, and achieved certain results, but China's extensive traditional the growth mode still exists for a long time. So the Chinese government is still the low carbon development as "planning" in 13th Five-Year. In view of this, based on the study of China's bored pile construction process of carbon emissions, details from the start, and strive to explore energy-saving emission reduction plan, promote the optimization and adjustment of the process, to ensure the sustainable development of Green China's construction industry in the long term. The building foundation part of the project about the whole building engineering quantity 1/4, the potential energy saving space to reach 5%-10%, research on building foundation construction visible part of the Righteousness is larger. Through the research on the construction of bored pile type carbon emissions impact, carbon emissions can obtain similar construction technology, can effectively guide the construction process and construction method perfect. This paper first analyzes the construction technology of bored pile, combined with the specific environment, labor, materials, machinery and other characteristics, the carbon emission factors of the process, and determine the amount of factor of pile unit quantity needed. With the support of carbon emission calculation standard, construction stage of bored pile base generated carbon emission model. Combined with the engineering practice and experience, material consumption, machinery, acquisition of carbon emission factors under the specific environment in the punching process based on the construction of carbon emissions. < > measurement standard "list statistics" and "building information model" concluded that carbon emissions, get bored pile construction in Yanping District carbon emission index of about 90.67kgC02/ M3 floating up and down; carbon emissions of construction equipment to foundation construction of carbon emissions 75.24%. Half the carbon emissions of punching machine based construction of carbon emissions. Based on the data of carbon emissions from the construction process of bored pile under the TOSIS method and fuzzy comprehensive evaluation method as a research tool. Preparation of model, the model of project selection and evaluation, the energy-saving emission reduction objectives and measures of construction technology of bored pile based on the micro. In practice, the development of green building industry to contribute.
