Physical and mechanical properties of soilcrete mixtures: Soil clay content and formulation parameters

Estimation of Soil Loss Tolerance in Olive Groves as an Indicator of Sustainability: The Case of the Estepa Region (Andalusia, Spain)

“…The soil depth was obtained by means of an edaphic core, and edaphic samples were dried at 105 • C for 24 hours. For each treatment, porosity and moisture percentages were calculated based on the soil fraction lower than 2 mm, using dry and wet saturated soil weight estimations, and dry bulk density was measured according to Helson et al [40] (Equation (2)):…”

“…To apply the SLTI, we considered the soil formation and degradation rates over time [21], a soil depth (D SLTI) resulting from the difference between the total soil depth (D) and the useful soil depth of 20 cm assumed as a tillage layer (favorable soil layer for the root system of the plants) and the dry bulk density [40,45]. To calculate the SLTI, it is necessary to first estimate the weight of the soil per unit area according to the Moreira-Madueño criterion [19], following Equation (4):…”

Experimental and numerical investigation on a novel support system for controlling roadway deformation in underground coal mines

“…The results were summarized in Table 3. 25,26 The test results of Poisson's ratio varied from 0.21 to 0.26 with less regularity, and therefore, the value was set as 0.24 in this study. 25,26 The test results of Poisson's ratio varied from 0.21 to 0.26 with less regularity, and therefore, the value was set as 0.24 in this study.…”

“…It should be mentioned that the tensile strength of coalcrete was determined as 0.3 times of compressive strength based on the experimental results of grouted materials. 25,26 The test results of Poisson's ratio varied from 0.21 to 0.26 with less regularity, and therefore, the value was set as 0.24 in this study. 27…”

Morphological Characteristics and Soil Mechanical Properties of a Gully in the Dry-Hot Valley Region of Southwestern China

“…Ouyang et al [18] concluded that soil shear strength exerted a huge impact on soil erodibility, which thus could be used to determine soil erosion intensity. Helson et al [19] used soil shear strength to study the mechanism of soil splashing erosion and proved that there was a close relationship between the amount of splash erosion and shear strength. But there was little research on the influence of mechanical parameters on the gully, especially in the special geomorphology of a well-developed gully region.…”
