| 摘 要： | 为实现COMSOL与AVIZO联合仿真过程,以福州某地原状花岗岩残积土为研究对象,基于工业CT扫描与图像处理技术,建立真实土样的三维孔隙网络模型,并以单相水渗流场模拟为例,详细探讨了两者数据交互对接的可视化过程。结果表明：可视化联合仿真技术可以较好地实现细观尺度下的三维模型渗流场模拟和渗透率计算。研究方法丰富了现有土体三维重构仿真模拟的手段,为细观孔隙结构及流体渗流研究提供了新途径。

| Abstract: | In order to realize the joint simulation process of COMSOL and AVIZO, the undisturbed granite residual soil in a certain area of Fuzhou is the research object. Based on industrial CT scanning and image processing technology, a three-dimensional pore network model of real soil samples is established, and a single-phase water seepage field simulation is taken as an example to discuss in detail the visualization process of the data interaction between the two. The results show that: the visualized co-simulation technology can better realize the three-dimensional model seepage field simulation and permeability calculation at the meso scale. The research method enriches the existing methods of 3D reconstruction simulation of soil, and provides a new way for meso-pore structure and fluid seepage research. |
