摘要:

为倡导将绿色环保理念融入铁路隧道行业,丰富完善绿色铁路隧道的综合评价系统,对铁路隧道全生命周期绿色等级评价体系展开研究。首先,明确绿色铁路隧道的内涵与定义,将铁路隧道的生命周期划分为设计、施工、运营3个阶段,分析筛选不同阶段与生态环境之间的直接或间接影响因素,分三级层次构建铁路隧道全生命周期绿色评价指标体系。然后,选用层次分析法和熵权法综合计算得到评价指标的组合权重,依据灰色聚类评价理论与指标取值的数据结构特征,构造指标隶属于不同绿色灰类等级的白化权函数,并建立铁路隧道全生命周期绿色等级综合评价模型。最后,以广州市某典型铁路隧道为研究案例,经分析计算得到该案例的综合绿色等级为“绿色三星级”,符合绿色铁路隧道的建设要求,同时识别出非绿色或绿色等级不够理想的主要影响因素。

Abstract:

 To promote the integration of green and environmental protection concepts into the railway tunnel industry, and to enrich and improve the comprehensive evaluation system for green railway tunnels, the green level evaluation system for whole life cycle of railway tunnels is studied. First, the connotation and definition of green railway tunnels are clarified, and the life cycle of railway tunnels is divided into three stages: design, construction, and operation. The direct or indirect influencing factors between different stages and the ecological environment are screened, and a green evaluation index system for the whole life cycle of railway tunnels is constructed at three levels. Second, analytic hierarchy process and entropy weight method are used to comprehensively calculate the combined weights of evaluation indicators. Based on the grey clustering evaluation theory and the data structure characteristics of indicator values, a whitening power function is constructed for indicators belonging to different green gray class levels, and a comprehensive evaluation model for the green level of the whole life cycle of railway tunnels is established. Last, taking a typical railway tunnel in Guangzhou as a research case, the comprehensive green level of the case is analyzed and calculated to be "three star green", which meets the construction requirements of green railway tunnels. At the same time, the main influencing factors of non green or unsatisfactory green grades have been identified.
