Abstract：Relying on tunnel engineering crossing active fault fracture zone in high intensity regions in Western China，shaking table test of tunnel crossing multi-rupture surfaces was carried out. Based on acceleration，dynamic strain，displacement responses at measurement points and the state of cracks，the energy and damage characteristics of tunnel segmental lining structure and surrounding rock under incremental seismic wave excitation were studied. On basis of HHT transform method，the Hilbert marginal spectrum and transient energy spectrum demonstrated the damage trend of the surrounding rock and tunnel structure. The results are as follows：(1) The coseismic dislocation of the model soil surface is significant under ground motion，the major and minor rupture surfaces in fault fracture zone can be defined according to the dislocation displacement on both sides of rupture surfaces. (2) The damage evolution of tunnel structure near major rupture surface in footwall lagged behind that in hanging wall，the decrease in peak values of primary frequency and marginal spectrum of tunnel structure near the major rupture surface reaches the maximum of 29.1% and 87.1% under 0.4 g seismic excitation，and the extent of damage is much more serious than that in other parts. (3) Tunnel structure is mainly subjected to tensile cracking. The tensile cracking occurs in invert near major rupture surface in hanging wall under 0.2 g ground motion，while damage in arch waist appears under 0.4 g ground motion. (4) Surrounding rock in hanging wall decreases 34.7% in primary frequency under 0.5 g ground motion. The damaged degree significantly exceeds that of footwall and middle part of fault fracture zone. (5) According to the damage pattern of tunnel structure，invert is the weakest part which is easily cracked to varying degrees. The seismic design coupling damping design of tunnel invert are needed to focus on strengthening. Tunnel structure near interface between hanging wall and fault suffers most under ground motion，while tunnel in the middle of fault fracture zone suffers less. The seismic partition and fortification of tunnel engineering through fault fracture zone is required. The conclusions can provide certain reference basis for the seismic design of tunnels in high intensity seismic zones.
