The feature of typical multiple rotational loess landslides is: large scale, deep sliding face, three-five sliding face cascades, single landslide with the "plough" structural character of behind high and sheer-middle subdued-front tilt. The main formation mode of landslide is creeping-sliding-tensile fracturing. The failure modes contain extensive rotation sliding, digressive rotation sliding and compound rotation sliding.
