在地铁项目的建设过程中,地铁线路设计是至关重要的一环,因此对地铁设计线路优劣的判断不可忽视。运用量化分析法以及层次分析法,首先,将地铁选线时必须考虑的城市规划、地质情况和通行能力三个指标纳入模型系统,并从每个指标中选取合适的二级计算指标,分别为灰色关联度、岩土地质总评价以及实际通行能力等;其次,分析影响二级指标的主要因素,对每个二级指标进行定量计算,并利用百分制计算一级指标得分;最后,按重要程度将三个指标加权求和,为方案评测出一个综合评分。
In the subway project construction process, the subway line design is a crucial part of the design of the metro line of the merits of the judge can not be ignored. Using quantitative analysis and analytic hierarchy process, firstly, the three indexes of urban planning, geological conditions and traffic capacity that must be considered in metro line selection are included in the model system, and the appropriate secondary calculation indexes are selected from each index, which are Gray relational degree, general geotechnical evaluation and actual traffic capacity. Secondly, the paper analyzes the main factors affecting the secondary indicators, quantifies each secondary indicator and calculates the first-level indicators using the percentage system. Finally, according to the degree of importance The three indicators weighted sum, for the program evaluation of a comprehensive score.
