【摘要】：随着我国城市化步伐的加快,环境问题已经成为我们密切关注的重要话题,混凝土作为建筑中的常用材料,几乎涉及我们日常生活的各个方面,如何减少混凝土对环境影响程度已成为绿色建材中的一个重要课题。绿色混凝土作为一种新型的建筑材料,因其能降低水泥用量,具有良好的力学性能和耐久性,节约能源,与自然和谐共存等特点而逐渐引起人们的关注。为了更加合理的、科学的识别和指导绿色混凝土的制备和使用,建立符合我国基本国情的绿色混凝土综合评价体系就显得尤为重要,文章以绿色建材评价原则为基础,主要完成了以下几方面的工作:(1)通过大量阅读文献和资料,了解现阶段国内外绿色混凝土的发展水平,在分析国内外绿色混凝土发展的基础上,解释和说明了在我国建立符合国情的绿色混凝土综合评价体系是非常必要的。(2)系统分析绿色混凝土所具有的特点,确认出其与传统混凝土的区别,并掌握建立绿色混凝土综合评价体系的原则及方法,为指标体系的构建打好基础。(3)通过分析绿色混凝土的特点及其特殊性,选择出满足要求的各级指标,对各级指标进行了具体说明,并建立了综合评价指标体系,说明了指标体系中各级指标的隶属关系,同时制定出相应的评价准则及要求。(4)以建立的指标体系为基础,建立综合评价模型,综合评价模型以灰色聚类分析法为模型主体,将灰色关联分析法和主成分分析法进行组合,以求较为客观的确定出综合评价的各级指标权重。为了满足评价模型使用的一般性,模型主体方法采用打分制,打分过程以原始测量数据为基础,以各二级指标为依据进行;同时,为了满足评价过程的客观性,文章以原始数据作为确定组合权重的来源,结合灰色关联分析法和主成分分析的特点,使权重的确定过程更加准确和客观。(5)为了检验指标和模型的可行性,文章选取一种绿色混凝土作为评价对象,将其代入指标体系和模型进行综合评价。(6)总结综合评价体系所涉及的范围和内容,分析说明综合评价模型的创新点,同时,说明文章的不足,为今后的研究打好基础。
[Abstract]:With the acceleration of urbanization in our country, environmental problems have become an important topic that we pay close attention to. As a common material in architecture, concrete involves almost every aspect of our daily life. How to reduce the impact of concrete on the environment has become an important issue in green building materials. As a new kind of building material, green concrete has attracted more and more attention because it can reduce cement content, have good mechanical properties and durability, save energy, and coexist harmoniously with nature. In order to identify and guide the preparation and use of green concrete scientifically, it is very important to establish a comprehensive evaluation system of green concrete, which accords with the basic conditions of our country. This paper is based on the evaluation principle of green building materials. Mainly completed the following aspects of work: 1) through a large number of reading documents and materials to understand the current level of development of green concrete at home and abroad, on the basis of analysis of the development of green concrete at home and abroad, This paper explains and explains that it is very necessary to set up a comprehensive evaluation system of green concrete in our country, which is suitable for the national conditions.) the characteristics of green concrete are analyzed systematically, and the difference between green concrete and traditional concrete is confirmed. The principles and methods of establishing the comprehensive evaluation system of green concrete are grasped, and the foundation is laid for the construction of the index system. By analyzing the characteristics and particularity of green concrete, the indexes at all levels that meet the requirements are selected. In this paper, the index system of comprehensive evaluation is established, and the subordinate relationship of the indexes in the index system is explained. At the same time, the corresponding evaluation criteria and requirements are worked out based on the established index system. The comprehensive evaluation model is established. The grey cluster analysis is the main body of the comprehensive evaluation model, and the grey relational analysis method and principal component analysis method are combined in order to objectively determine the weight of each level of comprehensive evaluation. In order to satisfy the generality of the evaluation model, the main body of the model adopts a scoring system, the scoring process is based on the original measurement data, and the evaluation process is based on the secondary indexes, at the same time, in order to satisfy the objectivity of the evaluation process, In this paper, the original data is used as the source of determining the combined weight, and the characteristics of grey relational analysis and principal component analysis are combined to make the process of determining the weight more accurate and objective. 5) in order to test the feasibility of the index and model, This paper selects a kind of green concrete as the evaluation object, and puts it into the index system and model for comprehensive evaluation. It summarizes the scope and content of the comprehensive evaluation system, analyzes and explains the innovation of the comprehensive evaluation model, at the same time, Explain the insufficiency of the article, lay a good foundation for the future research.
