Análisis de la propagación y distorsión de señales eléctricas en suelos arcillosos remoldeados de la formación Tosagua mediante procesamiento computacional de señales.

Abstract

This study examines the mechanical behavior and electrical signal propagation in remolded clay soils from the Tosagua formation under controlled moisture conditions (0%, 5%, 10%, and 15%). Experimental tests evaluated unconfined compressive strength, elastic moduli, and the characteristics of electrical signal propagation (amplitude, frequency, and distortion). Data were processed using computational techniques and statistical analysis to develop predictive models correlating mechanical and electrical properties. The results indicate that compressive strength and elastic moduli significantly decrease with increasing moisture, showing reductions of 68% and 73%, respectively. Electrical signals exhibited a 50% attenuation in maximum amplitude (from 1.2 V to 0.6 V), attributed to dielectric absorption and resistive losses, while dominant frequencies remained stable. Inverse correlations were identified between signal amplitude and mechanical properties, demonstrating the potential of electrical signals as indicators for soil characterization. Although limited (R² of 0.06 and 0.13), the predictive models provide practical tools for assessing soil behavior in dynamic contexts. This study introduces a novel approach by combining experimental and computational modeling to analyze moisture effects on clay soils. The findings are relevant to foundation design, geotechnical monitoring, and stability assessments in regions with moisture-sensitive soils. They establish a robust foundation for future research that integrates mechanical and electrical properties in more complex scenarios.
