【摘要】 皖南山区是安徽省滑坡地质灾害最为发育地区,且滑坡类型多样、成灾机制复杂。为建立一个适宜于该区的滑坡综合分类体系,文章按照滑坡体的物质组成、结构特征和成因机制3个层次进行了分析。首先根据滑坡体的物质组成将其划分为岩体、土体和古滑坡3个大类,再按坡体结构特征和成因机制进一步细分为6个小类,并分别对这些类型的滑坡特征和形成机制进行了研究,以期为该区的滑坡灾害防治提供参考和借鉴。更多还原

【Abstract】 Mountainous area of southern Anhui is the most landslide-prone area in Anhui Province,where the landslide is diverse and the formation mechanism is complicated.In order to establish a comprehensive classification system which suits this area,landslides are analyzed in view of their material composition,structural features and genetic mechanism.First,landslides are divided into three major categories according to their material composition,namely rock,soil and ancient landslide.Then landslides are further subdivided into six small classes according to the slope structural features and genetic mechanism.The characteristic and formation mechanism of each of these types of landslide are studied so as to provide a reference for the prevention and control of landslide hazard in this area.更多还原
