跨海集群工程节能减排关键技术研究

Study on Key Technologies of Energy Saving and Emission Reduction in Cross-sea Cluster Project

港珠澳大桥跨海集群工程囊括跨海桥梁、沉管隧道、离岸人工岛等多个领域。跨海集群工程由于建设期及运营期能耗巨大,国内外尚无节能减排的成套技术指导工程建设,成为制约跨海集群工程持续发展的瓶颈之一。本文依托港珠澳大桥跨海集群工程建设和运营过程,采用理论研究、数值分析及模拟测试等多种方法,开展了集群工程节能减排指标体系和长大沉管隧道通风、照明、人工岛运营节能减排关键技术研究,成果支撑了工程项目节能减排目标的实现。

Hong Kong-Zhuhai-Macao Bridge cross-sea cluster project includes cross-sea bridge,immersed tunnel,offshore artificial island and other parts. Due to huge energy consumption during the construction and operation period of this cross-sea cluster project,there is no a complete set of technologies to guide the construction,which is one of the bottlenecks restricting the sustainability development of the cross-sea cluster project. Based on the construction and operation period of Hong Kong-Zhuhai-Macao Bridge project,various methods including theoretical research,numerical analysis and simulation test are adopted to study the energy saving and emission reduction index system key technologies,including ventilation and lighting for immersed tunnel, energy-saving and emission reduction for artificial island. The result supports the accomplishment of the project's energy-saving emission reduction target.
