贵州省德江县高位隐蔽性地质灾害形成条件分析

Analysis on Formation Conditions of High Concealed Geological Disasters in Dejiang County, Guizhou Province

山区坡陡山高,地质复杂,地质灾害隐患较多,制约着当地的经济社会发展。因此,文章以贵州省德江县为例,对高位隐蔽性地质灾害形成条件进行分析,以期为地质灾害的评估与防治工作提供一定的参考。研究表明:地质灾害常常是由多种因素综合影响而产生的,既有外部的诱发因素,又有自身内部的因素。内部自身因素有地质灾害体所处的地形地貌条件、地质构造条件、岩土体工程地质条件,外部诱发因素有人类工程活动、气象水文条件等因素。

Steep slopes, high mountains, complex geology,and many geological disaster hidden dangers in mountainous areas restrict the local economic and social development.Therefore, this paper takes Dejiang County of Guizhou Province as an example to analyze the formation conditions of high concealed geological disasters, in order to provide some references for the evaluation and prevention of geological disasters. Research shows that geological disasters are often caused by a combination of various factors, including both external factors and internal factors. The internal factors include the topographic and geomorphological conditions, geological structure conditions, and geotechnical engineering geological conditions of the geological disaster body location.The external inducing factors include human engineering activities, meteorological and hydrological conditions and other factors.
