Abstract

Abstract

In this study, an optimized combination array with high resolution and signal-to-noise ratio was constructed from three conventional arrays of cross-borehole electrical resistivity to compensate for the shortcomings of sampling and electrical resistivity tomography with conventional arrays in curtain detection. The combined array was verified by numerical simulation for barrier curtain detection. It was applied to the barrier curtain detection of a landfill. The detection results of the two barrier curtains at the landfill showed that the main body of the barrier curtain possessed a uniform and complete low resistance zone at the early stage of consolidation, ranging from 0.001 to 0.06 Ω·m, and the grouting influence radius of the two barrier curtains were 0.55 m and 0.95 m, which met the requirements of curtain thickness and integrity. Combined with the hydraulic test of the core samples, it indicated the structure of the curtain barrier material in the two measurement areas was complete. The hydraulic conductivities were less than 10^-6 cm/s, meeting the hydraulic conductivity performance requirements for the contamination barrier. This study uses cross-borehole electrical resistivity tomography with the combined array to realize the efficient evaluation of the integrity and anti-seepage performance of the barrier curtain in the contaminated site.
