澳门轻轨东线工程跨海段隧道通风方案研究
摘要：以澳门轻轨东线工程跨海段的隧道通风方案为研究对象，通过在盾构隧道顶部设置单轨顶风道并在隧道中部设置轨顶风口，将隧道划分为2个通风区段。该项目利用车站风井和轨顶风道取代区间风井，并合理地布置风机、风井及配套设施；利用模式切换实现风机备用并减小土建规模。既满足了澳门地区特殊的设备备用要求和隧道通风效果，也极大限度地降低了投资。利用SES软件模拟验证了各参数配置的合理性和计算结果的可行性，为类似的跨海(江)隧道项目隧道通风设计方案提供了参考。

Research on tunnel ventilation scheme for sea-crossing section of Macao LRT east line project
Abstract: Taking the tunnel ventilation scheme for the sea-crossing section of the Macao LRT(light rail transit) east line project as the research object, the tunnel is divided into two ventilation zones by setting the single top-of-track ducts at the top of the shield tunnel and the rail top air outlet in the middle of the tunnel. This project adopts station air shafts and top-of-track duct instead of interval air shafts, arranges fans, air shafts and supporting facilities reasonably, and uses mode switching to realize fan backup and reduce civil construction scale. It not only meets the special equipment reserve requirements and tunnel ventilation effect in Macao, but also greatly reduces the investment. The rationality of each parameter configuration and the feasibility of the calculation results are simulated and verified by SES software, which provides a reference for tunnel ventilation design for similar sea(river)-crossing tunnel projects.
