摘要:
自然灾害长期以来严重威胁并阻碍着人类的生产和生活,特别是近年来由于山洪和地震等诱发的泥石流次生灾害,造成了大量的人员伤亡与财产损失.但随着人们对灾害研究的深入和计算机学科的发展,面对此类灾害人们不再被动.为实现对泥石流自然灾害的虚拟重现和分析预测,以计算机仿真为手段,GIS技术和流团模型为基础实现泥石流模拟系统.通过用户提供的地形数据,根据流团模型对泥石流进行仿真.利用GIS技术获得泥石流运动范围内的相关信息,并且对泥石流数据的动能、动量、流速、泥深的染色进行分析.系统对云南东川地区的泥石流流域进行仿真测试,得到了较好的仿真效果,可为实际应用提供依据
Abstract:
Natural disasters have always threatened the security of life and fortune of humanity. Particularly in recent years,such secondary disasters like debris flow caused by waterflood and earthquake have caused large casualties and property losses. But with the development of disaster research and computer technology,people are not passive when facing disasters. In order to achieve the natural disasters of deb-ris flow’s virtual reproduction and analysis forecasts,with the core of computer simulation technology,debris flow simulation system based on GIS technology and flow model is implemented. Topographic data provided by the user,according to the flow model to simulate the debris flow. By GIS technology,access to information in the debris flow within the range of motion,and analyze the debris flow data of the kinetic energy,momentum,velocity,deep mud stained. System is used in Dongchuan,Yunnan and has obtained good simulation results
