结合施工实践，开展海底隧道风化深槽施工技术的系统研究，从风化深槽采用超前地质预报的进一步探明、注浆堵水、堵水效果检查、超前预支护方案确定、开挖方法选择与确定、监控量测、突水涌泥应急对策等施工技术进行了认真研究，总结了方案和方法，供类似工程参考。

A systematic study is made on the construction technology for the deep weathered slots of subsea tunnels on basis of the construction practice. Construction technologies, including the advance geology forecasting of deep weathered slots, watersealing grouting, watersealing effect examination, determination of advance reinforcement schemes, determination of excavation methods, monitoring and measurement and emergency countermeasures for water/mud gushing, are carefully studied and effective construction schemes and construction methods are summarized in the paper, which can provide reference for similar projects in the future.
