Investigation of a loess-mudstone landslide and the induced structural damage in a high-speed railway tunnel

This paper presents a landslide that occurred in loess hills resulting in structural damage to the Zhangjiazhuang tunnel of the Lanzhou–Xinjiang high-speed railway line. The characteristics of tunnel deformation and structural damage are provided in detail. To ensure future safety of the tunnel, investigations consisting of field reconnaissance, borehole investigations, seismic activity and rainfall records analysis, and numerical simulations …
