Abstract In order to study the dynamic response and failure mechanism of mountain tunnel across fault zone and portal section under earthquake，a large-scale shaking table test was designed and carried out according to the Kangding—Zheduoshan tunnel project. Through this test，the dynamic response and failure mechanism of tunnel lining under different surrounding rock conditions were compared and analyzed. The research results show that：in this shaking table test，the acceleration，dynamic earth pressure and strain responses of tunnel lining were mainly affected by the surrounding rock conditions. The quality of surrounding rock around tunnel lining is poor，and its seismic response is strong. Under the action of three-dimensional seismic wave，the PGA amplification coefficient of tunnel lining decreases gradually with the increase of seismic wave amplitude，and the difference between dynamic earth pressure and strain increases gradually. The tunnel lining is under eccentric stress，and the conjugate 45° of cross section is the main stress direction. In addition，the longitudinal failure of lining structure develops from the portal to the deep surrounding rock，and each section of lining has the same failure mechanism. The failure process develops from“inverted arch→arch foot→arch shoulder→arch crown”. By comparing and analyzing the final failure modes of tunnel lining，it is found that the seismic damage of lining structure in portal section and fault zone section is more serious，and the seismic damage of substructure is obviously more serious than that of superstructure. Therefore，in the same tunnel project，it is necessary to pay attention to the seismic fortification of the mountain tunnel across the fault zone and the portal section，and focus on the seismic design of the lining inverted arch，arch foot and other parts.

Key words： tunneling engineering mountain tunnel fault zone portal section shaking table test dynamic response failure mechanism
