This work is supported by the Ministry of Science and Technology of China (No. 2004BA901A02). Three new theoretical models are proposed in this paper, which are three dimensional stability analysis model of landslides with single slip surface, three dimensional stability analysis model of landslides with multiple slip surface and failure time prediction model of landslides. Moreover, the kinetic rule of sliding body and rockfall are also discussed in this thesis.

在国家科技攻关计划"西部开发科技行动"重大项目(编号：2004BA091A02)的资助下，本文建立了单滑面滑坡三维稳定性分析模型、多滑面滑坡三维稳定性分析模型和滑坡失稳时间预测模型，同时还对滑落体和崩落体的运动规律进行了探讨。

The maximum run-out distance is 3200m. The three cases are studied from the Niuquangou rockslide-debris flow at the south west segment of the main seismic fault, the Chengxi rockslide at the middle segment of the main seismic fault and the Donghekou rockslide-debris flow at the north east segment of the main seismic fault.The three cases illustrates following common characteristics:(1)parent rockmass is broken under long geologic processing and weathered;(2) Rockmass was separately expanded and thrown under long-period strong ground vibration in which the vertical motion was predominant along the main seismic fault;(3)sliding mass was crashed at the exiting zone and transferred to fragment material;(4) The secondary landslide was triggered underneath the exiting zone due to the powerful crashing and shaving processes that provides more mass to debris body and cushion shape;(5) The a long run-out distance fragment flow is occurred under air layer lubrication. The air layer was pressed and turbulently flowed in the narrow-shaped valley, or laminarly flowed in the extensive flatland.

本文重点解剖了位于地震破裂带南西段的汶川映秀牛圈沟滑坡-碎屑流、位于地震破裂带中段的北川城西滑坡和位于地震破裂带北东段青川东河口滑坡-碎屑流3个典型实例，认为具有如下特征：1）岩性条件：母岩遭受长期构造动力作用，呈碎裂岩体，后期被强烈风化，岩体极为破碎；(2）抛掷效应：位于汶川地震主断裂带或附近，垂直加速度大于水平加速度，强地面运动持时长，岩体发生振胀和抛掷；3）碰撞效应：上部滑坡体发生高位剪出和高位撞击，致使岩体碎屑化；(4）铲刮效应：撞击作用导致下部山体被铲刮，形成次级滑坡，为碎屑流体提供了足够展翼和抛洒物源体积；5）气垫效应：碎屑化岩体快速抛掷导致下部沟谷空气迅速谷状圈闭和向下紊流，形成气垫效应，或者，在下部地形开阔地带压缩空气呈层流状态致使滑体凌空飞行。

The model can reflect the multi-sets feature of the rock masses in practice, consider the influence of the joint orientation and strength to the rock masses deformation feature, and simulate the simultaneous sliding, tension and close behaviors of the multi-sets jointed rock masses extending the joint surface, and reflect the plastic deformation induced the rotation of the principle stress axes. The result can be extended to fractured rock masses with arbitrary set joints.
