Summary:To efficiently improve the ground in an area covered with retained water over the deposited ash.SOLUTION: The ground improvement method of the ash disposal site in a state that used coal accumulated ash 102 is accumulated and retained water 102b covers the accumulated ash 102, includes the steps of: installing a partitioning frame 300 surrounding a target area for ground improvement in the ash disposal site; supplying a solidifying material 400 into the retained water 102b in the partitioning frame 300; stirring the retained water 102b in the partitioning frame 300; and draining the retained water 102b out of the partitioning frame 300. With this, the ground in the target area defined by partitioning frame 300 is improved.SELECTED DRAWING: Figure 1 【課題】堆積灰上に滞水したエリアを効率的に地盤改良できること。【解決手段】使用済みの石炭の堆積灰１０２が堆積し、堆積灰１０２上に滞水１０２ｂが張られた状態の灰処分場の地盤改良方法であって、灰処分場のうち地盤改良する対象範囲を囲む仕切り枠３００を設置し、仕切り枠３００内の滞水１０２ｂに固化材４００を投入し、仕切り枠３００内の滞水１０２ｂを攪拌し、仕切り枠３００内の滞水１０２ｂを排水することで、仕切り枠３００で規定した対象範囲を地盤改良できる。【選択図】図１
