【摘要】 白云质灰岩山体易产生崩塌,通过选取贵州白云质灰岩崩塌地区展开现场地质调查,查明了危岩体基本特征,结合该地区的地形地貌、地质构造、地层岩性,对白云质灰岩山体崩塌原因进行了初步分析。结果表明:区内白云质灰岩山体崩塌受到岩体结构、不利的地形、工程建设和降雨的影响,导致形成了山体危岩体;其危岩破坏主要模式为坠落式危岩和倾倒式危岩。该区域内的白云质危岩分布较多,深入研究其崩塌形成条件及破坏机制,对白云质灰岩崩塌的治理具有参考和借鉴意义。更多还原

【Abstract】 Dolomitic limestone mountains are prone to collapse. By selecting dolomitic limestone landslides in Guizhou Province and carrying out a field geological survey,the basic characteristics of dangerous rock masses are identified. Combined with the topography,geological structure and stratigraphic lithology of the area,the causes of dolomitic limestone landslides are preliminarily analyzed. The results show that the collapse of dolomitic limestone mountain in this area is affected by rock mass structure,unfavorable topography,artificial engineering activities and rainfall,resulting in the formation of dangerous rock mass in the mountain,and the main failure modes of dangerous rock are falling dangerous rock and toppling dangerous rock. There are many dolomitic dangerous rocks in this area. It is of practical reference and reference significance to study the formation conditions and destruction mechanism of this collapse.更多还原
