中文摘要：
滑坡的滑动过程是一个复杂的动态过程,库岸滑坡由于涉及到和涌浪的相互作用,其失稳运动过程难以进行数字化描述。基于重建的库岸滑坡体三维地质模型,运用三维极限平衡法分析滑坡的失稳诱发机制,为失稳运动的可视化仿真提供环境模拟背景。在判断滑坡可能失稳的前提下,针对库岸滑坡地面运动和水下运动的特点,提出库岸滑坡运动过程的数值模拟计算和可视化动态模拟分析流程,最终实现滑坡运动全过程的统一和三维可视化动态表达。实例分析验证了上述方法的可行性和实用性,模拟结果形象表现了滑坡体可能发生失稳时的运动面貌和涌浪过程,为滑坡失稳运动的研究提供了一种直观、实用的分析手段。
英文摘要：
The slope movement is a complex and dynamic process,especially the slope of the reservoir banks.During the moving process of reservoir slope,huge surge usually appears with it and has a great effect on it,so it is more difficult to describe the moving process of this kind of slope movement numerically than the others.Based on the rebuilt 3D geological model of slope of the reservoir banks,the mechanism of instability is analyzed by using 3D limit equilibrium method firstly,which provides an environmental background for the visual simulation.Then,in the case that the reservoir slope may be instable,the flow chart for digital and visual dynamic simulation of its movement is presented,according to the special features of two stages of the reservoir slope motion process,i.e.movement on ground and movement below water level.Finally,the whole process of reservoir slope movement is unified and its 3D visual dynamic expression is realized.The outcome of the application to an example gives a visual description of the slope motion process and the surge undulation at the same time,which demonstrates the feasibility and practicability of this method.Thereby it supplies a more convenient and visual analysis means for the research of slope motion process.
