Abstract

It is a well-known phenomenon that the color of sand changes due to moisture. As the moisture content increases, the sand will typically become darker. In our research, we are looking for the answer to the exact function according to which this darkening process changes and what relationship there may be between the different, initial (dry) soil colors and how this relationship can influence the evolution of the darkening process. Using the suitably chosen range of the color spectrum, we created a color parameter to characterize the color of the measured sandy soil, and then, in addition to determining the moisture content, we also looked for other uses of the color spectrum for sandy soil. Thus, based on the color spectrum and other input parameters, not only the moisture content can be calculated, but in the case of two components, the grain composition can also be determined.

砂质土壤水分含量与光谱的相关性研究
沙子因受潮而变色是一个众所周知的现象。随着水分含量的增加,沙子通常会变得更暗。在我们的研究中,我们正在寻找这个变暗过程变化的确切功能的答案,不同的初始(干)土壤颜色之间可能存在什么关系,以及这种关系如何影响变暗过程的演变。通过选择合适的光谱范围,我们创建了一个颜色参数来表征所测沙土的颜色,然后,除了确定含水量之外,我们还寻找了沙土光谱的其他用途。因此,根据色谱等输入参数,不仅可以计算出水分含量,而且在两组分的情况下,还可以确定颗粒组成。

期刊介绍: The Journal of Terramechanics is primarily devoted to scientific articles concerned with research, design, and equipment utilization in the field of terramechanics. The Journal of Terramechanics is the leading international journal serving the multidisciplinary global off-road vehicle and soil working machinery industries, and related user community, governmental agencies and universities. The Journal of Terramechanics provides a forum for those involved in research, development, design, innovation, testing, application and utilization of off-road vehicles and soil working machinery, and their sub-systems and components. The Journal presents a cross-section of technical papers, reviews, comments and discussions, and serves as a medium for recording recent progress in the field.
