基于物元法的高速公路绿色施工评价研究

Research on Evaluation of Expressway Green Construction Based on Matter-element Method

为有效减轻高速公路施工对环境的影响以及加快实现节能降碳的目标,本文从资源集约节约利用、污染控制、生态保护、品质提升、创新与宣传5个方面建立了高速公路绿色施工评价指标体系,选取模糊物元模型来判断绿色施工等级,并采用熵权法确定权重,以山东省某新建高速公路为例,验证了该模型的适用性和可行性,并与模糊综合评价法评价结果进行对比。结果表明,模糊物元模型应用在高速公路绿色施工评价中是合理可行的,且其评价结果精确度更高。

In order to effectively reduce the impact of highway construction on the environment and quickly realize the goal of energy saving and carbon reduction,this paper establishes an evaluation index system of highway green construction from five aspects:intensive and economical utilization of resources,pollution control,ecological protection,quality improvement and innovation and promotion.Fuzzy matter-element model is selected to judge the green construction grade,and entropy weight method is used to determine the weight.A new expressway in Shandong Province is taken as an example to verify the applicability and feasibility of the model,and the evaluation results are compared with that of fuzzy comprehensive evaluation method.The results show that the application of the fuzzy mature-element model in the evaluation of expressway green construction is reasonable and feasible,and the evaluation results are more accurate.
