【摘要】 随着地铁建设的发展,利用城市地下空间会越来越高,我们将会面临很多地铁穿越地下管线的问题,这必然是设计地铁和建设过程中无法忽视的难题。处理好管线改迁的问题,是地铁建设顺利开工的前提,也是能够如期完成的保障。在这方面,考虑到地铁站埋地管线与地铁建设的相互影响,优选合适的管线改迁布置方案就成为构建和谐的城市地下空间开发利用的一个重要环节。1)本文首先从指标产生的机理出发,采用演绎后更具针对性的“压力、状态、响应”PSR框架模型总结了地铁站管线改迁施工特点、管线空间位置要求、施工环境的约束条件、社会影响等方面的影响因素,然后构建了由管线改迁工程特点—改迁行为影响—社会管理约束三个方面组成的评价指标体系,并在此框架的基础上利用相关系数法对指标体系进行精简,为下一步改迁方案的优选奠定了工作基础。2)在对现阶段国内外评价方法的发展方向进行归纳总结之后,本文主要对解决多属性决策问题的几种常规评价方法在管线改迁方案评价问题上分别做了适用性分析,并提出了针对性更强的组合评价方法进行管线改迁方案评价,这也丰富了地铁站管线改迁方案评价的相关方法理论。3)针对研究对象的特点,本文采用组合评价对管线改迁方案优劣进行了评价分析。首先使用区间模糊数表达了每位专家对备选方案的评价矩阵,然后引入交叉熵理论定义了不同指标评价值的测度,并以此测度差异确定了指标权重。再综合考虑不同评审专家的水平差异,应用灰色关联分析以及熵最大化原则确定了专家权重大小。最后将备选方案的评价矩阵与指标权重和专家权重进行加权求和,得到了各个方案的综合评价值,确定出备选管线改迁布置方案的优选方案。4)本文应用集对分析理论重新表达优选方案的评价矩阵,明确了各个指标评价值对理想方案的满足程度,然后结合TOPSIS的思想最终得到指标到绝对理想解的偏离度序列。分析各指标的达成水平,对指标的改进和优化提出指导和建议。本文是对地铁建设中地铁站管线改迁问题的初步探索,为站点管线改迁方案的比选和优化提供了新的思路,具有一定研究价值。更多还原

【Abstract】 With the development of subway construction,the use of urban underground space will be higher and higher,we will face a lot of problems on subway through the underground pipeline,which can not be ignored during design subway and construction process.Deal with the problem of pipeline relocation has become a prerequisite for the smooth start of subway construction,and a pledge to complete the engineering as scheduled.In this regard,taking into account the interaction between the subway station buried pipeline and subway construction,selecting the appropriate pipeline to change the layout of the program has become an important part to construct harmonious urban underground space development and utilization.1)Based on the indicator generation mechanism,this paper summarizes the characteristics of the construction of the subway station pipeline,the location requirement of the pipeline,the constraint condition of the construction environment,the social influence of the construction environment with the help of the interpretation of more targeted "pressure,state and response" PSR framework model.And then constructs the evaluation index system composed of the characteristics of the pipeline change project-the influence of the change behavior-the social management constraint.On the basis of this framework,the correlation coefficient method is used to streamline the index system,which laid the foundation for the optimization of the next step.2)After summarizing the development direction of domestic and foreign evaluation methods at home and abroad,this paper mainly analyzes the applicability to pipeline relocation plan of several conventional evaluation methods that are always used to solve the multi-attribute decision-making problem,and put forward the more targeted evaluation scheme for pipeline relocation plan,which also enriches the relevant methodtheory of subway station pipeline relocation program evaluation.3)In view of the characteristics of the research object,this paper uses the combination evaluation to evaluate the merits and demerits of the pipeline.Firstly,we use the interval fuzzy number to express each expert’s evaluation matrix of the alternatives,and then introduce the cross entropy theory to define the measure of different index evaluation values,and determine the index weight with this measure difference.And then considering the difference of the level of different experts,apply the gray correlation analysis and the principle of maximizing entropy to determine the size of the expert weight.Finally,weight the evaluation matrix of the alternatives and the weight of the index and the weight of the experts sum and obtain the comprehensive evaluation values of the schemes,and the optimal scheme of the alternative pipeline relocation scheme is determined.4)In this paper,we use the set pair analysis theory to re-express the evaluation matrix of the optimal scheme,and clarify the degree of satisfaction from the evaluation value of the indicators to the ideal program,and then combined with TOPSIS theory to finally get the degree of deviation sequence from the index to the absolute ideal solution.After analyzing the indicators of the level of the indicators,give these indicators some guidance and recommendations to improve and optimize.This paper is a preliminary exploration of the problem of pipeline relocation plan around the metro station in subway construction,which provides a new idea for the comparison and optimization of pipeline relocation plan,and has certain research value.更多还原
