Abstract. Loess is a porous, weakly cemented, and unsaturated Quaternary sediment deposited in arid and semi-arid regions by the wind. It is widely and thickly distributed in China, making the Loess Plateau the largest bulk accumulation of loess on the Earth. However, the fragile geoenvironment in the loess areas of China causes frequent and various geohazards, among which, the Cracking-sliding (Beng-hua) is a typical failure mode because it causes the largest number of casualties each year. This study investigates the development pattern and main influencing factors of cracking–sliding failure to help in effectively preventing its occurrence and reducing losses. The following conclusions are derived: (1) cracking–sliding failures are prone to occur in rectilinear slopes, convex slopes, slopes with gradients greater than 60°, slopes with heights of 5 m to 40 m, and sunward slopes with aspects of 180° to 270°; (2) cracking–sliding failures occur mostly from 9 p.m. to 4 a.m. the next day, and concentrates in the rainy season (July to September) and freeze-thaw season (March to May); and (3) the more intense the human activities in the region, the greater the possibility of cracking–sliding failures.
