摘要
为了对西北寒旱地区的高铁桥梁绿色施工环境影响进行客观、量化的分析评价,提出适用于高铁桥梁在该地区施工阶段环境影响的区间分析方法。基于生命周期评价(LCA)理论,从施工阶段入手,结合铁路桥梁复杂特点以及西北特殊地理气候环境,先建立高铁桥梁绿色施工环境影响的评价框架和指标体系,为克服单一决策者的自身主观因素对评价结果的不确定性,然后采取群组专家共同评价,并对共同评价结果进行区间化,最后提出灰色关联TOPSIS法的环境影响评价模型得到评价结果。结合兰新高铁桥梁工程进行环境影响的实例运用,评价结果与工程实际资料高度吻合。因此,利用所提出的方法是有效的,可为今后高铁桥梁施工环境影响评价提供参考,也为桥梁绿色施工评价提供思路。
In order to objectively and quantitatively evaluate the environmental impact of high-speed railway bridge green construction in cold and dry areas of Northwest China,an interval analysis method suitable for the environmental impact of high-speed railway bridges in the construction period is proposed.Based on Life Cycle Assessment（LCA） theory,an assessment framework and index system for green environmental impact of high-speed railway bridges are established first,starting from the construction stage and combining with the complicated features of railway bridges and the special geographical and climatic environment in Northwest China. To overcome the subjective factors of individual decisionmakers,the uncertainties of their evaluation results are assessed by group experts and then the common evaluation results are compartmentalized. Finally,the environmental impact assessment model based on the gray association TOPSIS method is proposed to obtain the evaluation results. An application in Lanzhou-Urumqi high-speed railway bridge project shows that the evaluation results are in good agreement with the actual project data. Therefore,the proposed method is effective and can provide reference for future environmental impact assessment of high-speed railway bridge construction,and also offer new ideas for the green construction evaluation of bridges.
