To provide the combined footing of a pile and a diaphragm wall, by which the axial-force load of a building can be borne sufficiently in a soft ground, a response displacement in the case of an earthquake is decreased and a habitability is improved and upper skeletons are lessened by the diminution of an input to an upper structure or the classifications of the structures can be changed while the reduction of a pile section and a liquefaction countermeasure are carried out and it is possible that a total cost is reduced even by using the diaphragm wall and the terms of works are shortened.
In the combined footing 14 of the piles and the diaphragm wall, the combined footing 14 has a plurality of the piles 16a and 16b installed up to a bearing ground 22 and the diaphragm wall 18 integrally mounted together with the piles 16a, 16b, surrounding the piles, and is built at a place, where a soft ground is deposited in 30 m or more. The diaphragm wall 18 is disposed along the outer periphery of the building 10 having an approximately square form in a plan view, and formed in a depth shallower than the ground 22. The piles 16a are disposed even at the places of an outermost periphery in the diaphragm wall 18, and the axial-force load of the building 10 is borne to the piles 16a. Only a horizontal load in the case of the earthquake is borne mainly by the diaphragm wall 18.
