摘要
文章在调研了茅坪滑坡的基础上,对可能影响茅坪滑坡的因素进行了详细地分析研究,给出了茅坪滑坡地形、地貌、地裂缝调查现状、竖井地质素描、降雨规律、地表位移监测及其数据分析,并对几方面的信息进行综合分析,认为白岩崩塌、库水涨落及白岩中的采煤活动均不是茅坪滑坡变形的主要因素;由于滑坡上大量裂缝及水田的存在,降雨及水沟中水的入渗才是茅坪滑坡产生大变形的主要原因。
Based upon the analysis of insitu investigation such as cracks in the landslide, monitored data of surface displacements and rainfall, insitu geological sketch of shaft etc., the preliminary conclusion is reached that ① the falling of Baiyan cliff, fluctuation of reservoir water level and irrational coal mining in the Baiyan cliff are not the main factors caused the slide of Maoping; ② precipitation of rainfall and water in the gutters determines the deformation and displacement of Maopling landslide,because there are many cracks distributing in the landslide.
