    The slurry type shield method is the first choice for submarine soft-soil shield tunnel. If the slurry pressure is too high, it may lead to hydraulic fracturing of stratum in front of open face and cause accident of water gushing. The phenomena described as above, including mechanism of fracturing and the influence of slurry pressure on stratum fracturing, are studied. The achieved results show that, as slurry type shield is driven in submarine stratum, it is inevitable for some tiny cracks to exist in the strata, but the phenomena with/without water gushing has close relation with driving parameter, slurry characteristics, stratum characteristics and overburden thickness. Through theoretical analysis and shield model test, a semi-empirical formula of slurry gushing and anti-gushing method is put forward.
