Analysis of Mass Transportation around Underground Dam

第一年引入了具有高速视频捕捉实验中质量传输的“nexus”图像处理系统和工作站作为本项目的主要设备。工作站安装了UNIX操作系统，并加载了多套软件，为实验图像数据的数据处理和大众交通分析程序提供了运行环境。第二年，在上述系统基础上编制了质量输运有限元分析程序，并通过若干数值算例进行了验证。通过实验观察了物体的运动，验证了系统的有效性。结合现场实测资料，建立了分析地下坝周围土体运移的数值模型。最后，对研究结果进行了总结。

In the first year, the image processing system named 'nexus'with a high-speed video capturing a mass transport in the experiment and the work station are introduced as a main equipment of this project. The UNIX was installed on the work station and several sets of software were also loaded to provide an environment for running the data processing for the image data of experiments and the program for the analysis of mass transportation.In the second year, an FEM program for analyzing the mass transportation was developed on the above system and was examined through several numerical examples. An experiment was also carried out to observe the movement of the mass and the effectiveness of the system was demonstrated. A numerical model for analyzing the mass transportation around underground dam was developed by considering the data measured at an actual site. Finally, the results were summarized.
