摘　　要：在水下隧道施工中，覆盖层厚度不仅对其安全性起着决定性作用，而且还是决定水下隧道造价和长度的主要因素。介绍了水下隧道的优特点以及影响覆盖层厚度的主要因素，并结合本地地质着重对钻爆法施工覆盖层厚度的研究进行评述，提出运用解析公式和数值计算的方法确定合理覆盖层厚度。In underwater tunnel construction, the cover thickness not only plays the decisive role in its security, but also is a leading factor determining the underwater tunnel＇s cost and length, Advantages and difficulties of underwater tunnel and major factors influencing on cover thickness are introduced, Cover thickness for underwater tunnel by Drill - blasting Method related to local geology is presented emphatically, the method that combines analytical expressions with FEM to ascertain reasonable cover thickness is put forward.
