摘要
通过对安徽庐江龙桥镇地质灾害的类型、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,进一步查明地质灾害点和地质灾害隐患点,提出防治措施与对策。研究区主要地质灾害为滑坡、崩塌,共计17处地质灾害隐患点。其形成条件和诱发因素在全国地质灾害共性的基础上又呈现了区域特点。诱发地质灾害的内因主要为地形地貌条件、地层岩性、边坡结构类型和地质构造特征;外因主要为强降雨和人类工程活动。
Based on detailed field survey of the types, slope structures, lithologic characteristics, elevation distributions and terrain slopes of geo-hazards in Longqiao Town, statistical analysis was applied in further locating the spots of geo-hazards(risks), for which control measures were put forward. The main geo-hazards in the study area are landslides and collapses,17 in all, which show regional features in addition to the shared ones at the country level in terms of formation conditions and inducing factors. The internal causes of the geo-hazards are mainly the terrain conditions, stratigraphic lithology, slope structure types and geo-structure characteristics, and the external causes are mainly the heavy rainfalls and human engineering activities.
