The monitoring of water movement and transfer into the ground is very important for assessing mechanisms such as settlements, ground contamination, road collapse or landslides, to name a few. Soil moisture can be indirectly measured with different techniques. In this paper, a three-phase mixed α model of the soil dielectric constant is considered and the parameters are calculated considering a large database (experimental and from literature). Then, the physical meaning and interpretation of those parameters are described from the viewpoints of the soil index properties (i.e. soil type, dry density ρ _d and clay content).

粘土含量与土壤介电常数与干重的关系

监测水的流动和转移到地下对于评估诸如定居，地面污染，道路倒塌或山体滑坡之类的机制非常重要。土壤水分可以通过不同的技术间接测量。在本文中，考虑了土壤介电常数的三相混合α模型，并考虑了大型数据库（实验和文献）来计算参数。然后，这些参数的物理意义和解释从土壤索引属性（即土壤类型，干密度的观点来看，所描述ρ _d和粘土含量）。
