基于TRIGRS模型的浅层黄土滑坡破坏概率评价

ombined the TRIGRS model and the Rosenblueth point estimate method, a typical loess slope in Xing County, Shanxi Province, is used to study the impact of rainfall on the shallow loess landslide destruction probability. The authors determined the main parameter values through laboratory experiments and field artificial rainfall simulated test, calculated the destruction probability, and discussed the impact of different rainfall stages and gradients on the slope destruction probability in the region. The study shows this method is suitable for calculating the rainfall-induced shallow landslide. The landslide destruction probability distribution map got from this method, to a certain extent, can reflect the space distribution characteristics of landslide disaster in the region.
