摘　　要：隧道的成拱效应与覆盖厚度的大小有着密切关系。水下隧道的覆盖厚度对其建设的安全和造价起着重要作用。因此,对水下隧道的最小覆盖层厚度进行研究具有较大的工程意义。将重庆朝天门两江隧道与国内外一些知名海底隧道进行比较,得出其最小覆盖层厚度,对该工程的设计和施工具有重要参考价值。The arching effect of tunnel is closely related to the thickness of covering layer.The covering thickness of underwater tunnel plays an important role in safety and cost of its construction.Therefore,to investigate the minimal thickness of covering layer of underwater tunnel is greatly engineeringly signifi-cant.This paper compares the Chongqing Chaotianmen Liangjiang Tunnel with some famous submarine tunnels at home and abroad and obtains its minimal thickness of covering layer,which exhibits important reference value for design and construction of projects.
