| 摘 要： | 汶川地震诱发了大量的地震滑坡，其中地震碎裂滑动型滑坡是一种普遍的地震滑坡类型，滑动特征独特，动力机制复杂。以汶川县映秀镇牛圈沟滑坡为典型实例，从发育碎裂滑动的地貌、岩性、斜坡结构、地震作用等关键控制因素出发，阐释了牛圈沟滑坡的“滑动启动－碰撞碎裂－碎屑滑动－堆积停滞”4个阶段碎裂滑动中的7次折向过程，应用“地震启动-碎裂-加速”机理能够很好的解释地震滑坡超高速、滑程远、规模大的特点，具有一定的典型性和学科意义。

| Abstract: | A large number of seismic landslides have been induced by Wenchuan Earthquake,among which a universal seismic landslide type was fragmentation-sliding seismic landslide,with the unique sliding characteristics and complexity of power mechanism.In order to study the development characteristics of this kind of seismic landslide,Niujuan Ditch seismic landslide in Yingxiu of Wenchuan County was used as a typical example.Initially,the critical control factors of the formation for the fragmentation-sliding such as... |
