摘要

[目的

]

掌握西陵峡水田坝区域地质灾害发育特征及成因机制，为该区域地质灾害防治提供依据。[方法

]

对地质灾害的类型、规模、斜坡结构、岩性特征、分布高程、地形坡度进行详细的野外调查，并运用统计学进行梳理分析。[结果

]

研究区发育主要地质灾害为滑坡、崩塌（危岩）和不稳定斜坡，其规模以中小型为主。空间上分布不均匀，且集中分布在海拔高度300～800 m的区域，坡度20°～40°斜坡区域，并沿主要构造、断裂呈条带状发育；绝大多数灾害发育在侏罗系蓬莱镇组（J

p）、遂宁组（J

s）和沙溪庙组（J

s）岩性段中，以顺向结构岸坡中发育地质灾害居多；时间上，地质灾害多集中发生在降雨集中汛期6—9月。[结论

]

地质灾害成因机制的内在因素为地形地貌、地层岩性、岸坡结构类型和地质构造；外在因素为降雨、库水波动和人类工程活动。

Abstract

[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.
