| 摘 要： | 滑坡监测的目的是获取滑坡变形特征和演变过程。对于一些重要场地,判断其是否存在潜在滑坡时,深部位移监测是最直接和最有成效一种手段。通过在某厂房后坡两个监测断面设置5个深部位移监测孔,根据监测结果对滑坡体的范围、整体活动性、滑动方向、滑动面进行以及滑坡类型进行探讨和分析。监测结果表明:厂房后坡具有牵引式滑动特征,活动性明显; 坡体位移速度较大,雨季有加速变形的特征; 坡体前缘滑面已局部贯通,中、后部滑带也处于蠕动变形状态。

| Abstract: | The purpose of landslide monitoring is to obtain the characteristics and evolutionary process of landslides.For some important sites,monitoring in deep ground is the most direct and effective means to determine whether or not potential landslide exists,in this paper,five boreholes for underground monitoring are set on two profiles of a slope behind a hydropower plant.Slide area,slope activity,sliding direction,sliding surface and types of the landslide are discussed and analyzed.The monitoring results revea... |
