Tomography Analysis of Compacted Soil Using Electrical Conductivity

This paper reveals the soil compaction monitoring with tomography analysis as a determination of soil properties such as soil resistivity, soil moisture and angle of repose through Electrical Conductivity (EC). Estimation of soil compaction with electrical signal is becoming increasingly viable as commercial and technological solution in the construction of highway embankments, earth dams and many other engineering structures. To estimate the soil compaction in conventional soil monitoring technique is very tedious and costly with gathering a lot of sample of compacted soil for laboratory testing in geotechnical engineering. In this paper, the new idea is established to include 2-D tomography analysis with soil compaction monitoring using EC measurement system. Precision digital Multimeter and microcontroller handles the data acquisition, signal processing, control, and communication in this soil compaction measurement system. The performance of newly developed soil compaction measurement through EC system is estimated as reliable and robust with arrangement of tomography analysis in soil investigations. The importance of our research is to establish the reliable, faster and cost-effective soil compaction monitoring system with EC measurements in geotechnical site investigations.
