绿色公路技术LCA评价体系及效益分析

LCA Evaluation System and Benefit Analysis of Green Highway Technology

针对各类绿色公路技术难以横向比较的问题,文章从技术可行性、经济效益、节能减排效益等方面,提出建立绿色公路技术LCA评价体系,并以G312苏州西段工程为例进行综合效益分析,其综合效益最为显著,具备规模化、资源化、投资适宜的绿色公路技术;技术瓶颈问题的突破和创新,是推进绿色公路发展的根本动力;将绿色理念融入公路建设的全生命周期的前提,是因地制宜的前期规划布局研究,也是合理选择适宜绿色公路技术的基础。

Aiming at the difficulty of horizontal comparison of various green highway technologies,the article proposes the establishment of a green highway technology LCA evaluation system from the aspects of technical feasibility,economic benefits,and energy conservation and emission reduction benefits,and conducts comprehensive benefit analysis using the G312 West Suzhou project as an example.,Its comprehensive benefits are the most significant,with large-scale,resourcefriendly,and suitable investment green road technology;breakthroughs and innovations in technological bottlenecks are the fundamental driving force for the development of green roads;the green concept is integrated into the premise of the entire life cycle of road construction This is the study of the preliminary planning and layout according to local conditions,and it is also the basis for the reasonable selection of suitable green highway technologies.
