由于暴雨、河势变化、江水涨落等因素，长江堤防有许多岸坡失稳的事例。为了能够在计算机上计算和显示岸坡失稳发生和发展的动态过程，研制开发了一套计算机仿真软件系统。在该系统中，对地形地质数据、力学模型和有限元成果、计算机可视化技术、计算机图形学和多媒体技术进行综合运用，使堤岸失稳动态过程仿真得以实现。运行该系统就能在计算机上重现岸坡失稳的过程。

Due to rainstorms, river-regime change and fluctuations of water lever, many failures of embankments always happen along the Yangtze River. In order to simulate the failure process of the embankment dynamically,a set of software was developed. This system employs the geographic and geologic data, results obtained from mechanical model and finite element method, video technique, computer graphics and multi-media technique comprehensively to implement the simulation of embankment failure process. With this system, it is also possible to reproduce the embankment failure processes in computer
