Abstract：Based on complex function and groundwater hydraulics theory，the analytic solution for seepage field of subsea tunnels，which is made up of surrounding rock，grouting circle and lining concrete，has been deduced. Using the F4 entire strong weathering bursa of Xiamen subsea tunnel as engineering background，the influences of seepage parameters of surrounding rock，grouting circle and lining on water pressure on primary support and seepage discharge are studied. The study results indicate that the construction qualities of grouting circle and primary support have great influence on seepage discharge and water pressure on primary support，so the constructions of grouting circle and primary supporting should be emphasized. In case of the blocked drainage system and the decreasing seepage discharge，the water pressure on the primary and second support will be redistributed. Considering the theoretical analysis result and the data by real time monitoring of water pressure on site comprehensively，it is put forward that in the circumstance of limit drainage，the water pressure behind the primary support can be reduced to 1/3 of the full hydrostatic pore pressure.
