Schematic of the consolidation depth and calculation depth of the consolidation effectiveness index (\({R}_{c}\)): \({f}_{UC}(x)\) is the drilling resistance-depth profile of unconsolidated samples; \({f}_{C}(x)\) is the drilling resistance-depth profile of consolidated samples; j is the drilling depth of the point where the drilling resistance tends to coincide before and after consolidation.
