Abstract: At present, many subsea tunnels are under construction construction or to be constructed in China. Their costs are directly restricted by the minimum rock covers. Under the condition of the minimum rock covers, by applying fracture-damage, seepage and construction process model, the minimum rock covers are analyzed with the engineering geology and the water conditions of the subsea tunnel. At the same time, the minimum rock covers are affected by earthquake and blasting etc. Finally, by using project analogy method and numerical method and considering different kinds of factors effecting minimum rock covers, a better minimum rock cover can be chtained.

Key words: subsea tunnel, minimum rock covers, seepage, blasting, earthquake, construction process
