Abstract: Several investigations after earthquake indicate that areas where tunnels cross through faults are damaged severely. For a tunnel running through fault, an anti-seismic design concept is established and a joint of segmental lining is proposed in this paper, based on characteristics of ground motion energy transmission and release. A shaking table test was carried out to study the response of lining structures with joints under single fault movement loading mode, and combined action of normal fault rupture and subsequent seismic shaking based on the Longxi tunnel engineering. The test results show that effect of earthquake wave on the tunnel can not to be ignored, and the loading mode of combined normal fault rupture and subsequent seismic shaking was reasonable. The new joint designed segmental linings could alleviate the tunnel structure damage by self-adaptive deformation, and adjust the longitudinal deformation mode of the tunnel structure to improve the aseismic capability of the whole tunnel lining. Simultaneously the joints could mitigate the circumferential failure of lining, and weaken the seismic force transfer between segments to realize the local damage for tunnel lining. The damage influence length of the tunnel lining located in the hanging wall is 1.8 times of the tunnel span, while the damage influence length of the tunnel lining at the footwall is 1.2 times of the tunnel span. The tunnel damage of the hanging wall is mainly caused by the combined action of the normal fault movement and seismic shaking, while the damage of the lining is mainly affected by the ground motion at footwall.

Key words: tunnel engineering, segmental joint, dynamic response, fault movement, shaking table test
