摘要
我国山地众多,降水分布不均,干旱、暴雨频发,降雨山洪引发的滑坡灾害是重要的地质灾害之一,其巨大的破坏效应往往会对当地的环境及居民生命财产安全造成严重的威胁。降雨山洪引发的滑坡外在影响因素类型多样,地质、地形条件各不相同,滑坡诱发机理较为复杂。从滑坡预报模型、滑坡预警指标、滑坡预警系统3个方面,对国内外在这一领域的研究现状作以综述,并提出针对降雨的滑坡预报模型、滑坡变形诱因及机制、针对不同诱因的监控指标等研究的不足,并提出应在滑坡监控和预警中引入风险概念。
Because of many mountains,the uneven distribution of rainfall and drought frequent rainstorms in our country,the rainfall and flood triggered landslide is one of the important geological disasters. The huge damage effects will often pose a serious threat to the local environment and safety of life and property of residents. The landslide induced mechanism is very complex in virtue of the various types of external factors,geological and topographical conditions. This research was the hot and difficult problems of landslide research. Therefore,from the landslide prediction model,early warning index,early warning system,current research on this field at home and abroad were reviewed in this paper,and limitations of the study and suggestions were proposed.
