Abstract: Based on the investigation data of loess seismic damage over the past few decades, this paper summarizes the main types and characteristics of damaged loess slopes and establishes an evaluation method for the damage levels of loess slopes. Broadly speaking, damaged loess slopes could be categorized into two types: landslide and collapse accumulation bodies, and seismically cracked and damaged slopes. The first category includes loose accumulation bodies and blocky landslide bodies as subcategories, while the second category comprises steep slopes at the rear of landslides, seismically cracked but un-displaced slopes, and seismically cracked and down-dropped slopes as its three subcategories. According to the main damage features of seismically cracked and damaged slopes, considering the need for rapid assessment of landslide risks during the post-earthquake emergency period, the damaged slopes are mainly classified into three levels: mild, moderate, and severe based crack length, width, and depth. Landslide and collapse accumulation bodies, as a special type of damaged slope, are categorized under the severe damage level.
