拉线式滑坡地表及深部位移实时监测系统是测量滑坡地表及深部相对位移的监测仪器。通过对内蒙胜利露天矿东帮滑坡现场地质条件调查，分析了该滑坡的地质环境和滑坡特征，研究了内蒙胜利露天矿东帮滑坡发生的地质成因和环境成因。砂类土＋黏土＋砂质泥岩地层结构是胜利露天矿东帮滑坡发生的控制因素；露天矿不间断进行的开挖、爆破及其他外荷载是胜利露天矿东帮滑坡发生的影响因素；高强度、大量的降雨是胜利露天矿东帮滑坡发生的主要诱发因素。通过对布设在胜利露天矿东帮的地表及深部位移监测数据分析，该滑坡在暴雨之前的3个月，地表位移速率为1 mm·d-1，处于匀速蠕变阶段，并且由坡顶到坡底，地表位移略有增大，呈牵引式下滑特点，深部位移基本没有变化，暴雨后，两者均发生突变，3种不同深部布设的位移监测点有效地捕捉了滑面大致位置及错动距离，可为该类滑坡的深部位移监测深度确定提供一定的借鉴和参考。

Real-time monitoring system about surface and deep displacement of landslide is the relative displace-ment measurement instrument.On the basis of field investigation,the geologic environment and characters of Sheng-li landslide are studied in detail in this paper.Geologic origin and the environment origin are examined.The geolog-ical structure type(sand+clay+sandy mudstone)is the crucial factor.Continuing excavation,exploding and applied loading are the influencing factors.The high intense and large rainfall is the triggering factor.By analyzing surface and deep displacement monitoring data,the rate of surface displacement is 1 mm·d-1 three months before the rain-storm,at the stage of uniform creep stage.It appears traction landslide characteristics.At the same time,the deep displacement remains unchanged.After the rainstorm,both surface and deep displacements increase suddenly. Three deep displacement monitoring points with different depths effectively capture the approximate locations of the slip surface and dislocation distance,which can provide reference for determining the depth of deep displacement monitoring.
