GEOPHYSICAL METHODS FOR MONITORING SOIL STABILIZATION PROCESSES
Saneiyan, S., D. Ntarlagiannis, D Werkema, and A. Ustra.
Journal of Applied Geophysics 148:234-244(2018)
Carbonate precipitation is a promising method for stabilizing soil. Carbonate precipitation, typically in the form of calcite, is a naturally occurring process that can be manipulated to deliver soil strengthening results or permeability changes. This study investigated the ability of spectral-induced polarization (SIP) and shear-wave velocity for monitoring calcite-driven soil strengthening processes. The results support the use of these geophysical methods as soil strengthening characterization and long-term monitoring tools. Both methods are sensitive to calcite precipitation, with SIP offering additional information related to long-term stability of precipitated carbonate. Carbonate precipitation has been confirmed with direct methods, such as direct sampling and scanning electron microscopy.
