文摘

A landslide occurred on the morning of December 16, 2013, in Liujiabao village, Tianshui City, Gansu Province, China. The 260,000 m3 of landslide material traveled a distance of 190 m downslope and damaged a village road and several farmhouses before it stopped on the middle of the slope. These landslide materials are still threatening the lives and property of people in the downslope residential areas. A field survey revealed that this landslide was strongly affected by the geological setting. Six normal faults that extend from east to west developed in the Neogene mudstone of this region; these faults form a fault fracture zone with a width of 80 m. The authors performed a detailed investigation of the geological features of these six normal faults, and their spatial and faulting relationships to the landslide were examined. Finally, the evolutionary progress of the loess-mudstone landslide controlled by the fault fracture zone is discussed.
