PROBLEM TO BE SOLVED: To provide a soft ground improvement method capable of freely controlling load pressure on the ground, efficiently and reliably discharging gap water and air contained in the soft ground, and increasing the strength of the improved ground while being effective as a countermeasure against residual settlement to replace a banking for increasing a ground support force after ground improvement. SOLUTION: A large number of band-like tendons 31 are placed in the improved ground A. A plurality of expandable bag-like objects 32 are arranged on the upper surface of the improved ground A, and a support member 33 formed of a non-strechable material and connected to upper ends of the band-like tendons 31 is arranged in such a way as to extend over upper surfaces of the plurality of bag-like objects 32. By expanding the plurality of bag-like objects 32, the bag-like tendons 31 connected to the support member 33 are tensed to tighten the ground A between the band-like tendons 31.
