Abstract：Research purposes: Jiaozhou Bay Tunnel is needed to cross the seabed fault zone, but a little survey geological data are obtained because of the means limitation of engineering survey. The construction of seabed tunnel is conducted under conditions of seawater, water bursting passage(fault crack)，hydraulic pressure and construction disturbance, so the collapse and water bursting will happen if there is any carelessness in the construction, resulting in disaster outcome. Therefore, working out the feasible construction scheme is very important.
Research conclusions: (1)The geological forecast in advance should be done to seek the location, feature, scale and connectivity to the sea of the fault zone for the construction. ( 2 ) Drapery grouting for reinforcing seabed tunnel is the key technique which is important to the success of the work. ( 3 ) Installation of waterproof gate as the last waterproof measure is the most important safe measure. (4) Working out the emergence scheme is very necessary for ensuring the safety of the tunnel construction.
