【摘要】：渗流模型实验能够模拟天然岩土体中的渗流过程以及流体在介质中的运动规律,因此被广泛地应用于岩土、石油工程等多个领域的研究中.然而在传统的渗流模型实验中,由于模型介质的不透明,流体在介质中具体的渗流过程、扩散规律和赋存状态并不能被直观地观测到.因此在总结了可视化渗流实验的研究进展,归纳了现有成果取得的进展与存在的不足;提出了一种基于透明岩土相似材料,并结合光学观测手段、数字图像处理技术和示踪技术的可视化渗流实验新技术,对比分析了该技术与传统可视化渗流实验的优缺点.结果表明相较于传统渗流实验,该技术除了可以实现具体渗流过程的可视化观测外,还具有装置简单、易于操作、经济适用等方面的优点.表明利用这种材料开展渗流实验的可视化观测是可行的,为基于透明岩土材料的可视化渗流模型实验的开展奠定了理论基础.
[Abstract]:The seepage model experiment can simulate the seepage process in natural rock and soil and the movement of fluid in the medium, so it is widely used in many fields such as rock, soil, petroleum engineering and so on. However, in the traditional seepage model experiment, due to the opacity of the model medium, the specific seepage process, diffusion law and occurrence state of the fluid in the medium can not be observed intuitively. Therefore, this paper summarizes the research progress of visualization seepage experiment, summarizes the progress and shortcomings of the existing achievements, and proposes a kind of similar material based on transparent rock and soil, combined with optical observation method. The advantages and disadvantages of digital image processing technology and tracer technique in visualization seepage experiment are compared and analyzed. The results show that compared with the traditional seepage experiment, this technique can not only realize the visual observation of the seepage process, but also have the advantages of simple device, easy operation and economical application. The results show that it is feasible to use this material to carry out the visualization observation of seepage experiment, which lays a theoretical foundation for the development of visual seepage model experiment based on transparent rock and soil material.
