重庆韦家沟矸石山滑坡成因分析

An analysis of the cause of the Weijiagou coal waste dump landslide in Chongqing

摘要: 对韦家沟老矸石山进行勘察、研究,分析了矸石山的滑坡成因机制,揭示出特殊堆积散体构成、排弃地点条件、排弃强度等因素造成矸石山特殊堆积特征,导致矸石山具有二元空间结构、堆积地点水文地质条件改变、可能失稳滑动方式形成及呈现自组织临界性等性状,进而影响着矸石山稳定性的变化发展。在此基础上,采用极限分析上限法及数值模拟分析评价矸石山的稳定性,最后根据分析结果,提出相应的矸石山滑坡灾害防治措施。文章将定性分析与定量计算相结合,研究方法及结论可为类似矸石山地质灾害防治提供参考。

Abstract: The waste dump of coal mining is a representative artificial accumulation of bulky rock and soil materials.The landslide of waste dump has characteristics of its own.In order to prevent and control the landslide disaster of the Weijiagou waste dump in Chongqing,the characteristics,the developing background and the influence factors of the Weijiagou waste dump landslide were studied.The results indicate that many factors affecting the waste dump have accumulation characteristics of their own.Thes...
