The invention discloses a method for predicting the ultrasonic wave velocity of a stone body formed by reinforcing a loose gravel soil layer through floral tube grouting, and belongs to the technicalfield of rock engineering. The method comprises the steps of measuring the density, the water content and the specific gravity GS of the loose gravel soil layer needing to be reinforced, and calculating the porosity of the loose gravel soil layer; selecting a grouting floral tube according to the density, the water content, the specific gravity GS and the porosity of the loose gravel soil layer, measuring the hole distance between grouting holes in the side edge of the selected grouting floral tube, and calculating an average hole distance l; according to the designed grouting pressure p, thewater cement ratio w of the grouting fluid, the grouting time t and the ultrasonic wave velocity formula v of the grouting stone body, calculating the ultrasonic wave velocity v of the stone body formed by the floral tube grou
