The method comprises the following steps: step 1, constructing a full-waveform inversion initial model, and then performing single-scale inversion on the initial model by using a multi-scale elastic-wave full-waveform inversion method; step 2, performing multi-parameter weighted constraint and structure correction on the single-scale inversion result, so as to obtain a preliminary correction result; step 3, on the basis of a preset limiting condition, performing one-dimensional wave-velocity profile space structure correction and smooth constraint on the preliminary correction result, so as to obtain a secondary correction result; step 4, using the secondary correction result as an initial model of the next scale, and continuing to perform full-waveform inversion; and repeating steps 2-4 until the inversion of all the scales is completed, so as to obtain a full-waveform inversion result. The present invention can effectively solve the problems of the observation system being highly restricted, the detection data volume being relatively small, the offset distance being relatively small, and the multiplicity of solution of waveform inversion being high in terms of advanced detection of an excavation tunnel, thus improving the inversion effect.
