摘要

PURPOSE: An underground structure construction method is provided to easily maintain the perpendicularity between a horizontal structure of each floor and pillars by sequentially installing the pillars. CONSTITUTION: An underground structure construction method is as follows. A horizontal structure of first floor(30) is connected to the top of a center pile(20). An excavated part is dug out. Pillars between floors(40) are installed with one end fixed to the horizontal structure of first floor and the other installed on the bottom of the excavated part. A reinforced concrete foundation(14) is established on the floor of the excavated part. The pillars between floors are firmly secured on the reinforced concrete foundation. The center pile is eliminated.
