摘　　要：随着中国公路建设的发展,对施工环境的要求越来越高。以公路绿色施工为出发点,基于改良层次分析法,以某高速公路为例,在对公路工程环境影响因素进行分析的基础上,建立公路绿色施工环境影响评价模型,并通过工程实例验证了该评价模型的合理性和有效性。实例结果表明,节材与材料资源利用权重占比23.6%,环境保护、节水与水资源则分别为30.10%、24.5%。其中,边坡植被恢复率为最大影响因素,占比21.99%。研究提出的改良层次分析法可以客观、准确地反映工程环境影响的实际情况,从而为绿色施工提供参考依据。With the development of highway construction in China,the requirement of construction environment is higher and higher.Taking highway green construction as the starting point,this study is based on the improved analytic hierarchy process(AHP)and taking an expressway as an example.The environmental impact assessment model of highway green construction was established on the basis of analyzing the environmental impact factors of highway engineering.The results show that the weight of material saving and material resource utilization accounts for 23.6%,environmental protection,water saving and water resources are 30.10%and 24.5%,respectively.Among them,the vegetation restoration rate of slope is the most influential factor,accounting for 21.99%.The improved analytic hierarchy process(AHP)proposed in this study can objectively and accurately reflect the actual situation of the environmental impact of the project,so as to provide a reference for green construction.
