摘要
采用工程地质调查、钻探、地表变形监测和岩土试验等手段,对朱家店滑坡进行系统研究。发现此滑坡是一古滑坡复活形成的中型黄土滑坡,其诱发因素包括,堆放废弃矿渣和煤矸石,井口开挖形成临空面,及降雨汇集下渗。位移监测查明的滑动方向受控因素,一是西侧坡脚开挖形成的临空面,二是基岩面产状。
Engineering geological survey,drilling,surface deformation monitoring and geotechnical testing were used to study the landslide systematically.We discover it to be a medium-sized loess landslide as a result of an ancient landslide resurrecting.Its causes include coal residue and coal gangue piles,exposed surfaces formed by wellhead excavation and rainfall infiltration.Displacement monitoring shows the sliding direction is controlled by the exposed surfaces and the occurrence of bedrock surface.
