[Objective] The objective of this study is to investigate the development characteristics and mechanism of the regional geological hazards in Shuitianba area in the Xiling Gorge

and to provide the basis for preventing and controlling geological disasters in the region. [Methods] The type

size

slope structure

lithology

elevation distribution and slope gradient of geological disasters were investigated in detail

and statistical analysis was done. [Results] The major geological disasters include landslides

collapses(dangerous rock) and unstable slopes

and vary from small to medium-sizes. Spatially

regional distribution was not uniform

geological disasters more developed in elevation between 300~800 m with slope range from 20° to 40 ° and belt-like geological disasters developed along the main structure and fracture. The vast majority of geological disasters were formed in three stages: Penglaizhen formation(J3p)

Suining formation(J3s) and Shaximiao formation(J2s) in the lithology of Jurassic

and mostly distributed in bedding slope. The geological disasters mostly occur in flooding season from June to September. [Conclusion] The internal factors affecting the formation of the geological disasters include topography

lithology

slope structure type and geological structure while external factors include rainfall

reservoir water fluctuation and engineering activities by human beings.
