摘要
随着我国基础设施建设及地下工程快速发展,绿色公路逐渐被重视,隧道作为公路的重要组成部分,应用绿色公路理念进行设计至关重要。绿色公路理念要求依据地质选线和环保选线原则,保证项目填挖基本平衡,同时重视隧道洞口位置选择和进洞方式,兼顾洞口的美观和生态保护,隧道开挖土石方进行循环利用于路基填料及路面垫层,减少弃方量。隧道通风和照明系统用电量大,养护费用高,其节能减排措施是设计关注的重点,合理设置中水回用系统,体现了节能环保、循环利用的理念。以实际工程为依托,将绿色公路的理念应用到隧道设计中,并取得较好的经济效益、社会效益和生态效益,为类似工程提供借鉴。
With the rapid development of infrastructure construction and underground engineering in our country,green highway has been paid more and more attention.As an important part of highway,the tunnel should be designed with the concept of green highway,which is very important.According to the concept of green highway,the basic balance of project filling and excavation should be ensured by the principles of geological route selection and environmental protection route selection.Meanwhile,attention should be paid to the location selection of tunnel entrance and the way to enter tunnel entrance,taking the beauty and ecological protection of tunnel entrance into account.The excavation of earth-rock in tunnel should be recycled with the filling of roadbed bed and bed course of pavement,so as to reduce the abandoned amount.The electricity consumption of tunnel ventilation and lighting system is large,the maintenance cost is high,and its energy emission reduction measure is the focus of design attention.The concept of energy saving,environmental protection and recycling is reflected in the reuse system of reclaimed water with rational setting.Based on the actual project,the concept of green highway is applied in tunnel design,and good economic,social and ecological benefits are achieved,so as to provide reference for similar project.
