Seismic Stability Analysis of Loess Landslide Based on Orthogonal Test

IOP Conference Series: Materials Science and Engineering, 2020
Abstract A numerical model of a loess landslide is established by using numerical simulation method to simulate the stability of the loess landslide under earthquake load. The results show that the loess landslide is stable before the earthquake and instable under the earthquake.

Characteristics of loess landslides triggered by the 1927 Mw8.0 earthquake that occurred in Gulang County, Gansu Province, China

Frontiers in Environmental Science, 2022
The 1927 Gulang Mw8.0 earthquake was one of the largest earthquakes in Gansu, China, which triggered lots of loess landslides. However, the loess of the study area is atypical and different from that of the Loess Plateau.
