中国绿色公路建设与评估技术

Construction and assessment technology of green road in China

为了解决中国绿色公路建设中目前存在的建设理念不统一、评估体系不完善等问题,通过系统梳理中国绿色公路理念发展历程,明确绿色公路建设基本思想,进而确定绿色公路基本概念;全面调查了中国80余条和国外部分道路以绿色、景观、生态、节能、低碳为主题的绿色公路建设概况,总结分析了现阶段国内外绿色公路的建设特点,提出中国典型区域绿色公路建设的建议;基于绿色公路建设关键技术指标,提出现阶段绿色公路评估技术要求;从绿色理念、生态保护、资源节约、节能低碳、安全智慧、服务提升、品质建设7个方面,构建了包括7类一级指标、22个二级指标和58项评估内容的绿色公路评估体系,明确了不同地域自然环境及建设状况下的绿色公路可不参评指标,确定了绿色公路相应评估指标权重及评估分值计算方法,并运用该评估指标体系对中国某绿色公路进行了评估。结果表明:绿色公路评估体系可涵盖待评估公路的评价指标,具有较强的科学性和适用性;参评的绿色公路总分为64.06,在资源节约与服务提升等方面略有不足;绿色公路评估体系对中国绿色公路的发展建设具有指导意义,可为中国绿色公路的可持续发展提供借鉴。

In order to solve the problems in the process of China’s green road construction,such as inconsistent construction concepts and incomplete evaluation systems.The development of the green road concept in China systematically was reviewed. The basic idea of green-road construction,integrates the green-road concept was clarified,and the construction of green roads with the theme of green,landscape,ecology,energy savings,and low carbon for more than 80 green roads in China were investigated,as well as green roads abroad.A summary and analysis of the characteristics of green road in China were presented.Then,suggestions for green road construction in special areas were put forward.Based on the crucial technical indicators of green road construction,the technical requirements for evaluating agreen road under at present stagewere put forward.The evaluation indices system of green roads was set up from 7 aspects,such as green concept,ecological protection,resource conservation,energy-saving and low-carbon,safety and intelligence,service improvement,and quality construction.This evaluation indices system included 7 types of primary assessments 22 secondary indicators and 58 assessments.In this research,the green road non-evaluation indicators under different regional natural environments and construction conditions were defined,and the corresponding weights of the evaluation indicators and the green road evaluation score calculation method were determined.Meanwhile,the evaluation indices system was applied to evaluate a green road in China.The results show that the green road evaluation indices system can completely cover the indicators involved in the highway to be evaluated and has a strong scientific basis and applicability.The total score of the green road is 64.06 points,the green road falls short in resource conservation and service improvement.The green road evaluation indices system provides guidance for construction of China’s green road,and can provide reference for the sustainable development of China’s green highways.
