摘要
四川省南充市蓬安县位于川中盆地东北边缘,为典型红层丘陵-低山区,构造相对不发育,地质灾害主要为崩塌和滑坡,文章以蓬安县历年的巡、排查及实地地质调查资料为基础,系统分析了县域地质灾害发育与地质环境条件之间的关系,结果表明:蓬安县地质灾害发育的主要控制因素有地形地貌条件、工程地质岩组、斜坡结构、水文地质条件等,其中工程地质岩组、斜坡结构为地质因素,地形地貌、水文地质条件为环境因素。通过对蓬安县孕灾地质条件的分析,可以得出川中红层地区孕灾条件的一些共性,对于该区域其他区县,为地质灾害易发性区划及防治区划提供了重要的参考。
Pengan County in Nanchong City,Sichuan Province,is located in the northeast edge of the central Sichuan Basin.It is a typical red-bed hill-low mountainous region with relatively undeveloped structure.The geological hazards are mainly collapse and landslide.The main controlling factors of geological hazards development in Peng fan County are topographic and geomorphic conditions,engineering geological rock group,slope structure and hydrogeological conditions.The engineering geological rock group and slope structure are geological factors,while the topographic and geomorphic and hydrogeological conditions are environmental factors.Through the analysis of the geological conditions of geo-hazard formation in Peng'an County,some commonalities of geo-hazard formation in the red bed region of central Sichuan can be obtained,which provides an important reference for the zoning of geological disaster susceptibility and prevention and control for other districts and counties in this region.
