英文摘要：

Authors mainly summarized the research progress on submerged floating tunnel （SFT） at home and aboard in following four aspects： under the environment of water wave and current, the theoretical analysis model of interaction for SFT and under water wave, numerical analysis of the vortex induced vibration of anchoring system for SFT, dynamical response analysis of SFT due to seismic effect were studied. Structures of SFT, model tests on SFT for practical engineering under environmental loads of water wave and tests for drag coefficient and inertial coefficient of SFT under water current environment should be studied. Finally, some problems existed in submerged floating tunnel in the future were discussed, ie determining of load, structural design and analysis method, corresponding model test and safety research.
