【摘要】：近年来，随着国家城镇化政策的持续推进，城市建设用地日趋紧张、土地价格急剧攀升，从而带动了城市纵深的发展和地下空间的扩展，同时，也涌现出大量的深基坑工程。这些深基坑工程往往位于城市中心，既有建筑物和地下管网密集、施工场地狭小、交通繁忙；深基坑施工过程还涉及对天然地基及既有建筑物地基的扰动、地下水形态的改变，极易对城市环境造成不可逆转的污染和破坏。因此，绿色施工在城市深基坑工程施工过程中的推行成为了一项重要工作。本文针对城市深基坑工程绿色施工评价进行了研究，为我国城市深基坑工程绿色施工评价的发展和完善进行了理论与工程实践方面的探索。首先，本论文综合论述了我国当前城市深基坑工程绿色施工评价研究的现状，对比分析了国内外绿色施工评价研究的不同，并从博弈角度分析了绿色施工行为。将绿色施工理念引入到城市深基坑工程中，分析论述了城市深基坑工程各施工阶段的环境影响，城市深基坑工程绿色施工技术的运用以及城市深基坑工程各施工阶段绿色施工的控制要点，并提出了绿色施工PDCA循环管理。结合以上分析，以PSR框架模型为基础，采用定性分析与定量计算相结合，理论研究与实证分析相结合的方法，构建了城市深基坑工程绿色施工评价指标体系。然后，，根据所建立的绿色施工评价体系，明确评价指标体系的各个指标，并根据指标测算方法对其进行测算；同时，为了避免单一的主观赋权法和客观赋权法带来的权重确定不合理、不准确等缺点，本文采用能发挥主客观赋权法各自优势的综合集成赋权法来确定指标权重；在此基础上，运用灰色系统综合评价方法建立了城市深基坑工程绿色施工评价模型。最后，本文将城市深基坑工程绿色施工评价的综合理论方法应用于工程项目实践中，对青岛市香江旺角深基坑工程进行了系统地分析与研究，验证了本文所采用的综合研究方法与技术路线的科学性和可行性，得出符合实际的科学结论。为政府监管以及承包单位实施深基坑工程绿色施工提供理论支持，也为我国深基坑工程绿色施工的评价提供一种新的思路。
[Abstract]:In recent years, with the continuous promotion of the national urbanization policy, urban construction land is increasingly tense, land prices rise sharply, thus driving the development of the depth of the city and the expansion of underground space, at the same time, a large number of deep foundation pit projects have emerged. These deep foundation pit projects are often located in the center of the city, with dense existing buildings and underground pipe networks, narrow construction sites and heavy traffic. The construction process of deep foundation pit also involves disturbance of natural foundation and existing building foundation, change of groundwater form, It is easy to cause irreversible pollution and damage to the urban environment. Therefore, the implementation of green construction in urban deep foundation pit construction process has become an important work. In this paper, the green construction evaluation of urban deep foundation pit engineering is studied, and the theoretical and engineering practice is explored for the development and improvement of green construction evaluation of urban deep foundation pit engineering in China. First of all, this paper comprehensively discusses the current situation of green construction evaluation of urban deep foundation pit engineering in China, compares and analyzes the differences between domestic and foreign green construction evaluation research, and analyzes the green construction behavior from the perspective of game theory. The concept of green construction is introduced into urban deep foundation pit engineering, and the environmental impact of each construction stage of urban deep foundation pit project is analyzed and discussed. The application of green construction technology in urban deep foundation pit engineering and the control points of green construction in each construction stage of urban deep foundation pit engineering are discussed, and the PDCA cycle management of green construction is put forward. Based on the PSR frame model and the combination of qualitative analysis and quantitative calculation, the evaluation index system of urban deep foundation pit green construction is constructed by combining theoretical research with empirical analysis. Then, according to the established evaluation system of green construction, the indicators of the evaluation index system are defined and measured according to the method of index measurement; at the same time, In order to avoid the disadvantages such as unreasonable and inaccurate weight determination brought by single subjective weighting method and objective weighting method, this paper uses the integrated weight method which can give play to the respective advantages of subjective and objective weighting method to determine the index weight. The green construction evaluation model of urban deep foundation pit engineering is established by using the comprehensive evaluation method of grey system. Finally, this paper applies the comprehensive theory method of green construction evaluation of urban deep foundation pit engineering to the practice of engineering project, and makes a systematic analysis and research on the deep foundation pit project of Xiangjiang Mong Kok in Qingdao. The scientific and feasibility of the comprehensive research method and technical route adopted in this paper are verified, and the scientific conclusions are obtained. It provides theoretical support for the government supervision and the implementation of green construction of deep foundation pit by contracting units, and also provides a new way of thinking for the evaluation of green construction of deep foundation pit in our country.
