基于低碳环保高速公路施工经济效益研究

Study on Economic Benefit of Expressway Construction Based onLow Carbon and Environmental Protection

随着我国高速公路建设低碳施工关键技术的推广,其低碳环保施工经济效益逐渐显现,但如何实现低碳施工关键技术经济效益的量化成为当前难点。基于高速公路建设中隧道弃渣和表土资源流失等问题的分析,对其影响因素进行提炼,构建出低碳施工关键技术经济效益的量化模型和施工期关键技术综合经济效益模型。经广东平兴高速工程实例分析,量化的经济效益模型能够较好地反映平兴高速施工期节能减排实施效果,可为高速公路低碳施工关键技术实施效果的评价提供重要的理论基础。

With the promotion of key technologies for low-carbon construction in China′s expressway construction,the economic benefits of low carbon and environmental construction have gradually emerged.However,how to quantify the economic benefits of key technologies for low-carbon construction has become the current difficulty.Based on the analysis of tunnel spoil and surface soil resource loss in the construction of expressway,the influencing factors were extracted,and the quantitative model of key technology economic benefit of low-carbon construction and the comprehensive economic benefit model of key technology during the construction were constructed.According to the case analysis of Guangdong Pingxing expressway project,the quantitative economic benefit model can better reflect the implementation effect of energy saving and emission reduction during the construction period of Pingxing Expressway,and can provide an important theoretical basis for the evaluation of the implementation effect of key technologies for low-carbon construction of expressway.
