| Abstract | The corrosivity of the soil can be determined by resistivity. When Abuel-Naga et al. tested Bangkok soft clay in 2005, they proposed the clay's basic clay content and water content. The danger and necessity of corrosion prevention measures should be calculated before such a building is built. The resistivity value will decrease when the water in the void between the soil particles is saturated and should increase when the soil is dry. The ERI results show that the low resistivity that began the experiment due to an anion in the soil has saturated, producing steel pile corrosion. Water content is the main physical parameter that changes the resistivity of the soil. The 2D data runs the inversion model, and the results represent the zone of corrosion that occurred. 3D ERI results do not clearly understand the zone due to the anomaly of corrosion in the small zone around the steel pile. The zone of different resistivity was confirmed by the chemical results from ion chromatography testing. |
