Landslide Hazard Assessment Methods along Fault Zones Based on Multiple Working Conditions: A Case Study of the Lixian–Luojiabu Fault Zone in Gansu Province (China)

Traditional landslide hazard assessment methods generally use the same evaluation model to carry out assessments under different working conditions. Due differences in influence factors and calculation considered conditions, results obtained using traditional are from those of real-world scenarios. Therefore, research on optimal for conditions is important disaster prevention mitigation areas along fault zones. Taking section Lixian–Luojiabu zone Gansu province China as area, a was carried rainfall earthquake A method based fractal theory–information coupling proposed condition, an improved Newmark considering matric suction condition. Under information model, logistic regression theory regression–information model. Meanwhile, suction. Finally, ROC curve Kappa coefficient were used test accuracy these models determine The showed that had largest AUC value condition (0.856 0.807, respectively). second, values other three all lower than 0.8. This shows better 0.805 0.794, respectively, which larger These provide reference with similar characteristics.
