高位隐蔽性地质灾害分布特征及形成条件浅析--以贵州省兴仁县为例

Distribution characteristics and formation conditions of high-position hidden geological hazards:a case study on Xingren County,Guizhou Province

兴仁县高位隐蔽性地质灾害排查是贵州省开展高位隐蔽性地质灾害排查工作的八个示范县之一,“高位隐蔽性地质灾害”目前正处于不断摸索、探究的一个阶段。为在示范县排查工作中汲取成功的工作经验,能较好的指导下一步在全省铺开该项工作起到铺垫作用,本文以完成的贵州省兴仁县排查工作为例,重点对兴仁县高位隐蔽性地质灾害的分布特征及形成条件进行分析、总结,最终提出了“高位隐蔽性地质灾害”是发育于高陡斜坡体上,高差需大于100 m[1],具有规模大、隐蔽性高、危害性大的特点。因此,对深入研究、掌控高位隐蔽性地质灾害的发育特点,对地质灾害的认识、判断和防治的意义重大。

The study on high-position hidden geological hazards is now at the stage of trial and error.In order to learn from successful experience,and to better guide the investigation on high-position hidden geological hazards,based on the completed investigation work in Xingren County,Guizhou Province,this paper analyzes and summarizes the distribution characteristics and formation conditions of high-position hidden geological hazards in Xingren County,and proposes that the high-position hidden geological hazards usually develop on the high and steep slope body,with elevation difference greater than 100 m,and have the characteristics of large scale,high concealment,and high danger.Therefore,the in-depth study on the high-position hidden geological hazards is of great significance in the understanding,judgment and prevention of geological hazards.
