黔北煤田六龙井田红山滑坡成因初探
|
摘要
在分析了井田地层、构造、含水层、河流及泉水的基础上,对滑坡体的地貌特征进行了详细描述,认为形成滑坡的内在因素是地形及软弱岩层,外在因素是气候、水文、构造、地震。滑坡的形成过程包括孕破岩层、裂隙岩层、孕滑体岩体或岩层、开始滑动、大量滑动等几个不同阶段,并依次渐进。该滑坡形成于中早全新世(Q42-1),滑坡类型属切层滑坡。
Based on minefield stratigraphic,structural,aquifer,river and spring analyses,the paper elaborated on morphologic features of the landslide mass,recognized that the landslide formation internal factors have landform and weak intercalations,while external factors have climate,hydrology,geological structure and earth quake.The landslide formation process included stages of gestative broken rock mass,fissured rock mass,gestative sliding rock mass or strata,the beginning of sliding and sliding in large quantities,and followed in proper sequence and made steady progress.According to known data,estimated the landslide was formed during middle early Holocene epoch(Q42-1) and belongs to bed cross-cutting landslide type.
