绿色公路理念在海南高速公路设计中的应用

Application of Green Highway Concept in Design of Expressways in Hainan Province

基于G98环岛高速公路大三亚段扩容工程和山海高速公路等工程设计实例,从生态环保选线、挡墙及桥隧设置、隧道洞渣及自采碎石加工利用、下部结构装配化、服务区设置等方面,总结了绿色公路理念在高速公路设计中的应用,从统筹资源利用、加强生态保护、着眼周期成本、实施创新驱动等方面实现环保、节约的目的,为今后类似项目提供一定参考。

In the paper,based on of the highway design practice in the expansion project of the Greater Sanya Section of the G98 Island Ring Expressway and the Wuzhishan-Haitangwan Expressway,the application of green highway concept in design of expressways are concluded in terms of ecological and environmental protection oriented route selection,settings of retaining wall and bridge and tunnel,tunnel slag and self mining crushed stone processing and utilization,substructure prefabrication and assembly,as well as setting of service area.The environment friendliness and less consumption of resource are realized from the aspects of overall resource utilization,strengthening ecological protection,focusing on cycle costs,and implementing innovation driven,so as to provide some reference for similar projects in the future.
