摘要
为充分掌握夏琼寺景区内地质灾害对文物及居民造成的威胁,在详细调查的基础上,分析了地质灾害的分布规律及发育特征,并研究了地质灾害的成因机制.结果表明,区内地质灾害类型较多,主要可分为滑坡、不稳定边坡、崩塌和泥石流4类,且就影响范围而言,泥石流与滑坡灾害的影响范围相对最大,2者是区内的主要地质灾害;同时,区内各类地质灾害变形迹象明显,多处于欠稳定状态.影响区内地质灾害的因素较多,地质灾害的发育是多种影响因素综合作用的结果,后期综合防治应具系统性和全面性.
In order to fully grasp the threat of geological hazards to cultural relics and residents in Xiaqiongsi scenic spot,this paper,based on detailed investigation,analyses the distribution and development characteristics of geological hazards in Xiaqiongsi scenic spot,and studies the formation mechanism of geological hazards in Xiaqiongsi scenic spot.The research shows that there are many types of geological hazards in the area,which can be divided into four categories:landslide,unstable slope,collapse and debris flow.In terms of the impact scope,the impact scope of debris flow and landslide hazards is relatively large,and it is concluded that the two are the main geological hazards in the area.At the same time,there are clear signs of deformation of various geological hazards in the area.Obviously,most of them are in an unstable state.There are many factors affecting geological hazards in the region,and the development of geological hazards is the result of the comprehensive effect of multiple factors,and then the comprehensive prevention and control in the later period should be systematic and comprehensive.
