摘要
武汉三阳路长江隧道是世界上首座城市道路与地铁合建的盾构隧道,具有超大直径、高水压、小间距、地质条件复杂、建设条件困难等特点,总体设计难度大。文章针对三阳路长江隧道公铁合建的工程实践,结合其工程建设环境条件、隧道施工安全与风险、两种不同交通方式本身的技术要求及在运营防灾救援方面的相互影响等因素,对隧道平面、纵断面、横断面、疏散救援等部分关键技术进行了分析研究,确定了合理的工程总体设计方案,可为类似工程提供参考。
The Wuhan Yangtze River tunnel on Sanyang Road, the first rail-and-road combined shield tunnel in the world, has encountered some difficulties in overall design because of its extra-large diameter, high water pressure, small spacing, complicated geological conditions, and difficult construction conditions. Thus, based on the interactive factors of environmental conditions, relevant construction safety and risk, technical requirements for rail and road, and disaster prevention and rescue during operation, this paper analyzes some key design techniques for the tunnel plane, longitudinal profile, cross section, and evacuation and rescue in order to reduce the risks of construction and operation. Additionally, a proper overall design scheme is proposed, providing a good reference for similar projects in the future.
