摘　　要：清江水布垭坝址附近大岩淌滑坡处理是枢纽建设的重大工程问题之一。为此在采取有效工程治理措施的同时,针对滑坡工程地质特征,进行了滑坡的安全监测,并对其变形机理进行了分析。监测的主要项目有:抗滑桩的钢筋应力监测、滑坡深部位移监测、地下水监测等。深部位移监测初期成果表明:滑坡前部抗滑桩和中后部深部位移变化较大,应引起各方的高度重视。The control of Dayantan landslide near the damsite of Shuibuya project on Qingjiang river was one of the important engineering problems on the hydropower project construction.While effective structural measures were taken for the landslide control,the landslide body's safety monitoring was conducted in view of the engineering geological characteristics of the landslide,and the deformation mechanism of the landslide was also analyzed.The main terms of landslide monitoring include: stresses of reinforcement bars in sliding-resisting piles;displacements of deep-level portions of the landslide body;ground water levels,etc.The early-stage observation results show that the displacements of the sliding-resisting piles in the front portion of the landslide body and the deep-level displacements in the middle and rear portions of the landslide body varied greatly,which should bring to related departments more attentions.
