级配不连续透明土可视化及渗透实验研究
|
Abstract:
土体内部的渗流问题较为复杂，传统的观测方法不能很好地观测到实验的过程。随着透明土技术的发展，利用配置与天然土体性质相近的透明土代替天然土进行实验观测成为一种新兴的技术手段。本文通过此方法设计物理实验，建立模型，实现对土体内部渗流等问题的可视化研究。并将实验所获得的迂曲度参数代入经典的渗透系数模型计算公式从而得到土体的渗透系数，最后通过计算所得渗透系数之间的对比，探索其随土体自身物理特征变化而变化的趋势和规律。
The seepage problem in the soil is more complex, and the traditional observation method cannot observe the experimental process well. With the development of transparent soil technology, it has become a new technical means to replace natural soil with transparent soil. In this paper, physical experiments are designed and models are established by this method to realize the visual research on the internal seepage of soil. The tortuosity parameter obtained from the experiment is substituted into the classical calculation formula of the permeability coefficient model to obtain the permeability coefficient of the soil. Finally, through the comparison between the calculated permeability coefficients, the trend and law of its change with the physical characteristics of the soil itself are explored.
