Landslide Susceptibility Assessment Using a Machine Learning Model with VAE-CDM Sample Augmentation: A Case Study of Southeastern Xizang

Landslide susceptibility mapping in alpine regions with limited data has two persistent obstacles: too few recorded landslide cases and the questionable reliability of non-landslide samples. We address these issues with a hybrid generative framework—a Variational Autoencoder (VAE...

Identification of Unstable Rock Blocks and Rockfall Hazard Assessment on a Karst Steep Rock Slope Using UAV Photogrammetry

Steep rock slopes are widely distributed in the karst mountainous regions of southwestern China, where structurally controlled rockfalls frequently threaten transportation infrastructure and human safety. Accurate identification of unstable rock blocks (URs) and quantitative asse...

Mechanism of lateral resistance in obliquely inclined bedding rockslides: a case study of the Shanyang rockslide

Obliquely inclined bedding rockslides are prone to severe casualties and great economic loss for its less visible apparent dip slide. The lateral resistance is key to understanding the failure mechanism of obliquely inclined bedding rockslides. Nevertheless, few studies have cond...

Seepage and Stability Analysis of Loess Landslides Under the Coupled Effects of Long-Term Irrigation and Fissures

Long-term agricultural irrigation in the loess platform region of Northwest China has raised the groundwater level and triggered numerous irrigation-induced loess landslides. The widely developed fissures in loess provide preferential pathways for irrigation water infiltration an...
