Early detection of potential landslides along high‐speed railway lines: A pressing issue

Yaru Zhu,
Haijun Qiu,
Peng Cui
et al.

Abstract: Early detection of landslides is important for prevention and mitigation of landslide disasters. Especially, accurately identifying potential landslides along high‐speed railway is becoming a pressing issue for operation safety of high‐speed railway. Here, 161 Sentinel‐1A satellite images from March 2017 to September 2022 were acquired to detect potential landslides along the Lanzhou‐Urumqi high‐speed railway (LUHR) in Qinghai. Results show that rainfall is the main cause for the transition from secondary cree… Show more

“…Higher moisture content reduces the preload required for creep damage to occur, while higher axial strain increases the time required for each load [97]. Precipitation is the most important catalyst for the acceleration of creep in landslides [26]. However, the need for further research is highlighted by the paucity of studies investigating the effect of creep on the stability and formation mechanism of loess landslides.…”

“…Restoration of the deformation baseline and cyclic monitoring are carried out by real-time monitoring using real-time kinematic (RTK), precise point positioning (PPP), and static baseline technologies supported by the Beidou positioning system and GPS [25]. Based on Sentinel-1A satellite images, Zhu et al [26] used hotspot analysis to cluster the average line-of-sight deformation rate of hills along the Lanzhou-Urumqi high-speed railroad line between 2017 and 2022 and proposed a framework for the early identification and monitoring of landslides.…”

“…In this context, Interferometric Synthetic Aperture Radar (InSAR) technologies could be used to leverage our understanding regarding the concept of earthquake legacy (e.g., Bayer et al, 2018; Lacroix et al, 2020; Liu et al, 2022; Ma et al, 2023; Zhu et al, 2023). InSAR‐derived deformation time series could be used to investigate post‐seismic hillslope reactions instead of multi‐temporal landslide inventories, which provide discrete information in both spatial and temporal domains (e.g., Barth et al, 2020; Tang et al, 2016).…”
