Soil with low resistivity values < 100 Ωm has Organic Matter (OM): 4.27–4.80 %, Phosphorus (P): 50.23–54.22 mg/kg, Potassium (K): 290.0–340.0 cmol/kg, Total Nitrogen (TN): 62.20–65.11%, and pH: 6.8 to 6.9. Soil with resistivity values ranging from 100 to 600 Ωm has OM:...
In view of this, we take the hazardous Wanzhou area in the Three Gorges reservoir area as the research object, and apply high density grid resistivity method to measure resistivity values of different depth strata in the study area, to generate twodimensional resistivity profiles for the first ...
Four layers of rock-soil stratification interfaces with different resistivity values, revealed by electrical resistivity tomography, comprising loess-like pulverized clay, gravelly pulverized clay, and bedrock, existed at different burial depths in the longitudinal section. Borehole and displacement monitoring...
The shallow basement indicated low bearing capacity, with resistivity values ranging from 62.1 to 377.9 惟m. The presence of clay/clayey materials, linear features and the effect of rising water table within the influence zone underlined the pavement failure. This information will facilitate ...
Nitrate and turbidity levels exceeded the limits in some cases where the values were respectively above 10 mg/L and 5.0 NTU but sulphates, phosphates and solids were completely within the acceptable range. Related works conducted in other parts of the country showed elevated concentrations of some...
