摘　　要：为提升城镇密集区公路绿色建造水平,结合南(沙)—中(山)高速的项目特点及工程需求,将绿色发展理念贯彻到公路设计、施工、运营、养护和管理的全寿命周期,重点研发了公路桥群工业化智能建造、公路资源综合利用、滨海湿地区公路环境保护与粤港澳大湾区交旅融合设计等四类十项创新技术。其中,预制梁环形生产线、非标准八车道等为项目特色首创技术,初步构建了典型城市群绿色桥群公路技术体系,并对未来重点发展方向进行了展望,以期丰富和完善粤港澳大湾区绿色公路技术体系,为其他高度城镇化区域可持续发展提供参考。In order to improve the green construction level of highways in dense urban areas,the project characteristics and engineering requirements of the Nansha-Zhongshan Expressway were analyzed,and the concept of green development was implemented in the whole life cycle of highway design,construction,operation,maintenance,and management.The research and development of ten innovative technologies in four categories were highlighted,including industrial intelligent construction of highway bridges,comprehensive utilization of highway resources,environmental protection of highways in coastal wet areas,and integrated design of transportation and tourism in the Guangdong-Hong Kong-Marco Greater Bay Area.Among them,the prefabricated beam annular production line and non-standard eight-lane were the unprecedented technologies first used in the project.In addition,the technical system of green highway bridges in typical urban agglomerations was initially constructed,and the key development directions in the future were prospected to enrich and improve the technical system for green highway construction in the Guangdong-Hong Kong-Marco Greater Bay Area.This provided a reference for the sustainable development of other highly urbanized regions.
