摘　　要：武汉长江公路隧道是长江上第一条采用盾构法施工的大直径公路隧道,由于其规模大、水头高,以及水文、地质、工程条件特别复杂,因而面临着许多技术难点和风险。文章从工程的组织实施角度对该隧道工程可能遇到的技术难点和风险进行了分析,并提出了解决问题的建议。Wuhan Yangtze River tunnel is the first city road tunnel crossing the Yangtze River, big diameter slurry shield will be adopted for its construction. Because of the large scale construction and high water pressure head to be encountered, the tunnel is facing many technical problems and risk under the complicated hydrogeologic and engineering conditions. In this paper, the problems and risk to be met with are analyzed, with some suggestions put forward.
