The invention discloses a method for reinforcing a soft ground by combining vacuum preloading and surcharge vibration rolling. The method comprises the following steps of: inserting a vertical draining plate, paving a medium-coarse sand cushion layer, digging a sealing ditch, and simultaneously, paving a horizontal draining pipe; and paving a horizontal water filtering pipe in the medium-coarse sand cushion layer, paving a vacuum film on the medium-coarse sand cushion layer, backfilling the sealing ditch, setting a measurement mark, arranging a vacuum pump, performing pressure stabilization after the vacuum pressure below the vacuum film reaches 85 kPa, performing backfilling by using pond residues, performing surcharge preloading, finishing surcharge preloading after a control requirement is met, and compacting soil on the surface layer through impaction and vibration rolling. Compared with the prior art, the method has the advantages that the soft ground is reinforced by combining vacuum preloading and surcharge vibration rolling, so that the original ground processing method through vacuum preloading or surcharge vibration rolling can be effectively improved, the cost of a ground processing project can be reduced, a construction period is shortened, and great significance is provided for improving the structural performance of the ground and the ground bearing capacity.
