【摘要】：滲流模型實驗?zāi)軌蚰M天然巖土體中的滲流過程以及流體在介質(zhì)中的運動規(guī)律,因此被廣泛地應(yīng)用于巖土、石油工程等多個領(lǐng)域的研究中.然而在傳統(tǒng)的滲流模型實驗中,由于模型介質(zhì)的不透明,流體在介質(zhì)中具體的滲流過程、擴散規(guī)律和賦存狀態(tài)并不能被直觀地觀測到.因此在總結(jié)了可視化滲流實驗的研究進展,歸納了現(xiàn)有成果取得的進展與存在的不足;提出了一種基于透明巖土相似材料,并結(jié)合光學觀測手段、數(shù)字圖像處理技術(shù)和示蹤技術(shù)的可視化滲流實驗新技術(shù),對比分析了該技術(shù)與傳統(tǒng)可視化滲流實驗的優(yōu)缺點.結(jié)果表明相較于傳統(tǒng)滲流實驗,該技術(shù)除了可以實現(xiàn)具體滲流過程的可視化觀測外,還具有裝置簡單、易于操作、經(jīng)濟適用等方面的優(yōu)點.表明利用這種材料開展?jié)B流實驗的可視化觀測是可行的,為基于透明巖土材料的可視化滲流模型實驗的開展奠定了理論基礎(chǔ).
[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.
