| Özet |
| Measuring cohesion (Co) as a simple and reliable factor with the fluidized bed approach to assess the inherent resistance of soils against destructive forces corresponding to the separation of particles from the soil mass is considered a promising research area in place of alternative methods by rainfall–runoff experiments. However, the approach has only been tested for very limited soil types, and there is a need to analyze its suitability for more diverse soil conditions, especially for cohesive soils having higher clay, organic matter, or lime contents. This study aimed to evaluate cohesion for twenty soil types representing nine different texture classes that differed significantly in terms of their intrinsic properties with an “Automated Soil Cohesion Measurement Apparatus”. This device was equipped with modern electronic sensor technologies designed to function and measure cohesion with the fluidized-bed approach. In the measurements, pressure drops that occur while the water pressure increases gradually as it passes through the soil mass are visually and electronically monitored and continuously recorded during the experiments with the help of precise differential pressure and weight sensors. Effects of the changes in intrinsic soil properties such as particle sizes, organic matter contents, and lime contents in terms of coagulation potentials on cohesive forces were observed with the designed apparatus. Related to that, the analysis of variance and the Fisher's least significant difference tests indicated that the cohesion (Co) and the flow velocity at fluidization (Vf) values were significantly different by soil type (p < 0.05). Fraction of the fine silt-sized particles (FNSI) was highly correlated with Co and Vf, and explained much of the variance for the cohesive conditions. In addition, the Co values in coarse-textured soil types with low cementing components and soils having greater sand contents were four times lower than those of heavy textured and clay-bound soils. The approach and the designed apparatus successfully simulated changes in internal soil conditions in terms of measured Co and Vf values. |
