Schematic of deterioration depth and calculation depth of drilling resistance (\(K\)): \({f}_{UD}(x)\) is the drilling resistance-depth profile of undeteriorated samples; \({f}_{D}(x)\) is the drilling resistance-depth profile of deteriorated samples; i is the drilling depth of the point where the drilling resistance begins to stabilize.
