摘要
飞剑潭水库库区地处萍乡—乐平坳陷带北缘,地质灾害较发育。选取该地区地质灾害进行调查研究,分析了地质灾害的分布规律及其成因特征。调查结果显示:该地区地质灾害类型主要为土质滑坡;从地质灾害发育的时空分布规律分析,具有集中群发性特征。空间上主要分布于缓坡地带、人类工程活动强烈区,同时沿主要构造线发育;从时间上分析,地质灾害发育主要集中于雨季,其中2014年5月最为严重。因此,库区地质灾害发育特征受控于地形地貌、地层岩性、地质构造及人类工程活动等因素综合作用,同时降雨是地质灾害的主要诱发因素。
Feijiantan Reservoir area is located on the north edge of Pingxiang-Leping Depression where geological disasters are developed. This article analyzes the distribution and formation characteristics of the geological disasters of this region to provide theoretical basis for the construction of Feijiantan water conservancy park and the geological disaster prevention plan. The survey results show that the main type of geological disaster in this area is soil landslide featuring group-occurring. The occurrences are mainly distributed in ramp areas, intense human activity areas and major tectonic lines and are mainly concentrated in the rainy season with the most serious occurring in May 2014. Therefore, the development and distribution of geological disasters are the combined effects of topography, lithology, geological structure and human engineering activities, and rainfall is a major predisposing factor.
