摘要
铁路工程绿色设计,是实现其绿色发展的重要手段。目前,铁路工程各专业大多从某个工程应用角度出发,主要集中于绿化和污染防治案例研究,很少从系统角度出发研究铁路工程绿色设计。铁路工程要实现某一绿色指标,须从系统角度,各专业协同设计。因此,需要对铁路工程绿色设计目标进行特征分析,明确铁路工程绿色设计目标实现的主要途径。为此,首先从铁路绿色设计概念出发,采用目标层次分解、问卷调查等方法,对铁路工程绿色设计的目标进行逐层分解,将资源节约划分为土地节约、能源节约、材料节约及水资源节约等,将环境保护分解为生态环境保护、水土环境保护、大气环境保护、人文景观提升及其他环境保护等方面,并进一步细化第3层次的属性特征,明晰了铁路工程绿色设计的目标特征及内涵。通过对铁路工程各专业的设计流程进行分析,依据相关设计规范和标准,梳理各专业在不同设计阶段的主要绿色设计要点。基于jieba分词工具将绿色设计目标特征及各专业的绿色设计要点划分为多个词向量,采用主观赋权的方法确定特征分词的权重,并定义语义信息匹配度,将铁路工程绿色设计目标与铁路工程设计的各专业进行匹配,明确铁路工程各绿色设计目标得以实现的主要途径,为铁路工程各专业系统实现总体绿色设计提供依据。
Green design of railway engineering is an important means to achieve its green development.At present,most railway engineering specialties focus on a specific engineering application perspective and mainly on case studies of greening and pollution prevention,with little research on green design of railway engineering from a systematic perspective.It is necessary to collaborate and design from a system perspective among various specialties to achieve a certain green indicator in railway engineering.Therefore,by analyzing the characteristics of green design goals in railway engineering,the main implementation approaches to achieve green design goals in railway engineering are clarified.To this end,starting from the concept of railway green design,the objectives of railway engineering green design are decomposed layer by layer using methods such as target hierarchy decomposition and questionnaire survey.Furthermore,the resource conservation is divided into land conservation,energy conservation,material conservation and water resource conservation,and the environmental protection is decomposed into ecological environment protection,soil and water environment protection,atmospheric environment protection,cultural landscape improvement and other environmental protection aspects.The attribute features of the third level have been refined,and the target features and connotations of green design in railway engineering have been clarified.Subsequently,by analyzing the design processes of various specialties in railway engineering,the main green design points of each specialty in different design stages are sorted out based on relevant design specifications and standards.Finally,based on the jieba segmentation tool,the green design target features and the green design points of each profession are divided into multiple word vectors.The weight of feature segmentation is determined based on the subjective weighting method.In addition,the semantic information matching degree is defined to match the green design goals of railway engineering with various specialties of railway engineering design.Through this study,the main implementation approaches to achieve the green design goals of railway engineering have been identified,and the research can provide a basis for the overall green design of various professional systems in railway engineering.
