摘　　要：简述厦门海底隧道斜井,在土石交界段采用超前帷幕预注浆的方法进行堵水、加固,克服了该段围岩含水量达到50%、土体自然涌出呈流塑状、无法正常施工的困难,安全顺利地通过软弱含水的土石交界段,为隧道海底风化深槽帷幕注浆积累一些施工经验。It summarizes that the Xiamen subsea tunnel＇s inclined shaft uses the curtain pre-grouting method in the earth-rock junctional section to carry on the water shutoff, the reinforcement in advance, which overcomes the difficulty that surrounding rock＇s water content of this section reaches 50%, soil bodies gushing out naturally in liquid which denies normal construction, passes through this soft and watery section safely and gaines some construction experience of curtain grouting at weathered trough of subsea tunnel.

关 键 词：措施斜井 土石交界段 超前帷幕注浆
