Discussion of Visual Technique for Seepage Experiment Based on Transparent Rock-Soil Material

Abstract

Introduction:Due to the fact that the model experiment can simulate the flow process and movement law of fluid during the seepage experiment, seepage model experiment was widely applied to study the hydraulic characteristics of rock-soil mass and transportation of ground water and pollutants. While due to the opacity of the model medium in traditional seepage experiment, the flow process, diffusion law and occurrence state of fluid can not be observed intuitively during the experiment. Method:A new technique of seepage model experiment based on transparent rock-soil material (TRSM) was introduced in this paper, combined with optical observation method, digital imaging process technology and tracer technique, so as to realize the visual observation of seepage process. Results:The advantages and disadvantages compared with the traditional experiment were analyzed and the theoretical foundation for carrying out the seepage experiment based on TRSM was established.
