摘　　要：为研究澳门地区轻轨东线隧道通风系统,分别对工可方案及相关规范开展了详细分析与研究;结合内地地铁设计经验及相关规范,对工可阶段隧道通风系统进行了优化,减少了隧道风机、活塞风井的设置数量,将跨海段通风区段由3段优化为2段,为避免隧道建设对海域环境的影响,取消中间风井设置,通过合理组织通风,将跨海段隧道上部风道由双风道优化为单风道,隧道直径由13.5m优化减小到12.1m,上述优化设计,既满足了隧道通风效果及澳门地区特殊的设备要求,也较大幅度地降低了投资,全线隧道通风系统整体造价减少约46%,跨海段盾构隧道造价减少约49%。在工期方面,隧道全线工期缩短8~10个月,其中跨海段工期可缩短4~6个月。另外,分析了隧道风机设置、耐火、不同工况下的气流组织,为类似工程隧道通风设计方案提供了参考,同时全面介绍了澳门地区轻轨东线隧道通风系统。To explore the tunnel ventilation system of the Macao Light Rail East Line,a detailed analysis and research were conducted on the feasibility study plan and relevant specifications;Based on Chinese mainland metro design experience and relevant specifications,the tunnel ventilation system during the feasibility study stage has been optimized,reducing the number of tunnel fans and piston air shafts.The ventilation section of the cross sea section has been optimized from 3 sections to 2 sections.To avoid the impact of tunnel construction on the marine environment,the middle air shaft has been canceled.By organizing ventilation reasonably,the upper air duct of the cross sea section tunnel has been optimized from double air ducts to single air ducts,The diameter of the tunnel has been optimized from 13.5m to 12.1m.The above optimized design not only meets the ventilation effect of the tunnel and the special equipment requirements in Macao,but also significantly reduces investment,the overall cost of the ventilation system for the entire tunnel has been reduced by about 46%,and the cost of the cross sea tunnel has been reduced by about 49%.In terms of construction period,the entire tunnel construction period has been shortened by 8-10 months,with the cross sea section shortened by 4-6 months.In addition,the setting of tunnel fans,fire resistance,and airflow organization under different working conditions were analyzed,providing reference for similar engineering tunnel ventilation design schemes.At the same time,a comprehensive introduction was given to the tunnel ventilation system of the Macao Light Rail East Line.
