PROBLEM TO BE SOLVED: To provide a new ground reinforcing method capable of surely supporting the lower end of a pile to be driven on a supporting ground even if the supporting ground is inclined or formed in an irregular state and more surely reinforcing the ground. SOLUTION: In the ground reinforcing method equipped with a depth measuring process measuring the depth of the supporting ground 10, an excavation process excavating the lower side of a foundation of each existing structures 1 to form a space 5 and a pile driving process driving a plurality of piles 7 (7A, 7B and 7C) are driven in the ground 8 while respectively and gradually adding them to the direction of the length of the pile 7 while supporting the existing structure 1 in positions near to a detached house, an apartment house or a plant and other existing structures 1, before the lower end of the piles 7(7A) reach the depth obtained by the depth measuring process, a load instrument 9 is made to intervene between the upper end of the pile 7 (7C) adding thereto and the foundation 4 of the existing structure 1, and when a numeral value of the load by the load instrument 9 is in excess of a predetermined value, the pile driving process is stopped.
