Analysis of Seismic Damage Modes of Landslides Containing Tunnels under Horizontal Earthquake Action

Table 1

Typical engineering cases of tunnel crossing landslide under potential earthquake action.

Serial number	Tunnel’s name	Slope structure	System type	Disaster type	Remarks
1	Sunjiayai tunnel	Along dipping-layered slope structure	Orthogonal-through the slide	Tunnel excavation construction, continuous rain	Chongqing-Wufeng expressway
2	Zhongzhai tunnel	Along dipping-layered slope structure	Orthogonal-through the slide	Tunnel excavation construction, continuous rain	Linshuang highway
3	Songpan tunnel	Loose broken body slope structure	Skew-down slip body	High-intensity seismic action	Chenglan railway
4	Guojia tunnel	Slope structure with soft top and hard base bottom	Orthogonal system-underpass slip body	High-intensity seismic action	Baoji-Lanzhou high-speed railway
