重庆市地质灾害孕灾条件分析
|
Abstract:
重庆市地形地貌多样、地质构造复杂、地层岩性多样、水系广泛分布，具备地质灾害发育的良好条件，是我国地质灾害最严重省市之一，在西南地区具有典型的代表性。文章以重庆市地质灾害一万多处样本数据为基础，运用DEM数据、1:50地质图、1:50万地质构造纲要图、重庆市水系图等基础资料从地形地貌、地层岩性、地质构造和水系等因素分析了地质灾害与其相互关系，揭示重庆地质灾害发育的基本规律，为地质灾害防治和相关规划提供参考，具有一定的指导意义。
Chongqing has various landforms, complex geological structures, diverse strata and lithology, and widely distributed water systems. It has good conditions for the development of geological disasters. It is one of the most serious provinces and cities in China, and is a typical representative in Southwest China. Based on the sample data of more than 10000 geological disasters in Chongqing, and using the basic data such as DEM data, 1:50 geological map, 1:500000 geological structure outline map and Chongqing water system map, this paper analyzes the relationship between geological disasters and them from the factors of landform, formation lithology, geological structure and water system, and reveals the basic law of the development of geological disasters in Chongqing. It provides a reference for geological disaster prevention and related planning, and has certain guiding significance.
