Keyword束口型滑坡 运动特征 灾害预测
Abstract束口型滑坡为滑坡的前缘断面因受地貌条件约束而变窄且在平面上呈勺状的一类滑坡。这类滑坡分布较为普遍,特别在我国西部复杂地貌环境中更为多见。其运动特征为:1. 滑坡的运动速度较慢。2. 坡体一般在运动一段距离后,由于受束口的阻塞作用而停止运动。3. 部分坡体在剪出口处堆积,形成平卧“支撑拱”效应。4. 通常只有部分坡体物质能挤出束口。束口型滑坡的成灾方式具两种可能:1. 滑坡在首次滑动形成支撑拱后又再次滑动。2. 滑坡在滑动中有适量的粘土和水体参与,则迅速发生流态化,形成泥石流灾害。
Other AbstractA landslide of spoon shape is ones of forward keep within bounds for topography, narrowing section for movement. The landslides are distributed generally. Feature of movement are:
  1. The landslide velocity are slower.
  2. After slope bodies moved a distance, it will stop movement as one is blocked by narrowing section.
  3. Supporting arch of landslide is formed by slope bodies pile up at forward of one.
  4. Only part bodies are squeezed out narrowing section of landslide.
A landslide of spoon shape causes disaster way:
  1. After support arch are destroyed progressively, to lead to landslide take place again.
  2. When slope bodies put in water and clay, slope bodies form mud—rock flo
