Evaluating corrosivity of geomaterials in MSE walls: determination of resistivity from pore water chemistry
| 项目名称： | Evaluating corrosivity of geomaterials in MSE walls: determination of resistivity from pore water chemistry |
| 摘要： | The project team proposes that the electrical resistance of a geomaterial-water-air mixture can be modeled fundamentally as parallel electrical resistances of the geomaterial, pore-water, and air-voids. The team will develop a fundamentals-based model of pore water conductivity and soil-water resistivity as a function of pore water chemistry. These models will allow the project team to incorporate a fundamental mechanism for validating water quality and resistivity measurements and defining accurate values for acceptance criteria used for determining the corrosivity of geomaterials in metal-reinforced mechanically stabilized earth (MSE) walls. |
