摘要
丹寨县位于贵州高原向广西丘陵过渡的斜坡地带,山高坡陡,水系发育,地层岩性复杂多变,易发生地质灾害。为摸清地质灾害发育分布情况和孕灾背景,本文通过1:50000地质灾害详细调查,发现区内的地质灾害种类多,现有地质灾害78处,主要为滑坡、地面塌陷、泥石流、崩塌及不稳定斜坡。研究结果表明:地质灾害的发育与地形地貌、地质构造、工程地质岩组、斜坡结构、水文地质条件、人类工程活动等因素关系密切。通过对孕灾条件分析研究,有效提高了丹寨县地质灾害研究程度,为防灾减灾救灾工作提供了技术支持。
Danzhai County is located in the slope zone of the transition from Guizhou plateau to Guangxi hills.It has high mountains and steep slopes,developed water systems,complex and variable formation lithology,which is prone to geological disasters.To understand the development distribution of geological disasters and pregnant back⁃ground through a detailed survey of 1:50000,we found that there are many kinds of geological disasters in the area,there are 78 geological disasters,mainly landslides,ground collapse,debris flow,collapse and unstable slope.These results showed that the development of geological disasters are closely related to topography,geological structure,engineering geological rock group,slope structure,hydrogeological conditions,human engineering activities and other factors.This study has effectively improved the research level of geological disasters in Danzhai county and provided technical support for disaster prevention,mitigation and relief work.
