The invention discloses a method for detecting the processing and consolidation effect of a filled-in foundation of broken stones, dimension stones, and the like, which comprises the following steps: (1) adopting a testing means of multi-channel instantaneous surface waves; and (2) using a point distributing principle of small measure point space, uniform measure point distribution and large-area universal measurement, and meanwhile, stressing key parts and areas and adopting half arrangement and coverage during distributing measuring points and measuring lines; (3) adopting a data processing method of drawing an equivalent transverse wave speed isoline within different depth ranges of the whole site, calculating a characteristic value and the modulus of deformation of the bearing capacity of a layered foundation and drawing a corresponding isoline by inverting and layering the speed of a transverse wave so as to achieve the purposes of integrally and overall evaluating the consolidation effect of the filled-in foundation of the broken stones, the dimension stones, and the like difficult to evaluate by other detection methods and provide a reference for quality detection and base design.
