Abstract: In order to find a breakthrough in instability criterion method of tunnel engineering under seismic action, the principle, advantages and disadvantages and the application scope of the existing static and dynamic instability criterion methods of tunnel engineering were discussed, which strived to put forward practical and feasible criterion ideas. Firstly, the seismic response, damage mechanism, and the current overview of seven kinds of static instability criterion methods of tunnel engineering were described. Secondly, combined with the seismic response characteristics and the static instability criterion method of tunnel engineering, the development situation of dynamic instability criterion methods for tunnel engineering was elaborated from the qualitative judgment, theoretical inference, shaking table model test judgment. Then, the problems and shortcomings of the current dynamic instability criterion methods were summarized, such as lack of theoretical support for qualitative criterion method, the lack of research depth of the dynamic criterion theoretical method developed from the static criterion method, and the lack of special research on the shaking table failure test of the dynamic instability criterion method. Finally, the research prospect of the instability criterion method of tunnel engineering under seismic action were proposed, which provided a certain reference for researchers in this field.
