A method and system for advanced detection and optimization of tunnel resistivity based on depth resolution. The method includes integrating all acquired electrode measurement data into comprehensive set, calculating its model resolution matrix, and selecting plurality of electrode measurement data from comprehensive set to form initial set; adding measurement data of electrodes that are not in initial set to initial set to form plurality of temporary subsets; calculating depth resolution balance goodness function of temporary subset according to model resolution matrix, selecting temporary subset with optimal value of depth resolution balance goodness function as new initial set, and determining whether average relative model resolution of initial set meets optimization requirements; if requirements are not met, continuously updating temporary subset, otherwise outputting initial set; determining number and position of tunnel face measurement electrodes according to updated initial set, and obtaining effective observation mode of advanced detection of optimized borehole resistivity.
