METHOD FOR CONSTRUCTING UNDERGROUND STRUCTURE AND UNDERGROUND STRUCTURE
To provide a method for constructing an underground structure and an underground structure which are capable of shortening the construction period and suppressing the impact on surrounding infrastructure and buildings.SOLUTION: A method for constructing an underground structure comprises an earth retaining wall construction step in which an earth retaining wall 11 is constructed in the ground so as to surround a construction area of the underground structure, a support pile driving step of driving support piles 5 into an outer peripheral portion 3 within the construction area, a sheathing wall construction step of constructing a sheathing wall 22 at a boundary between an outer peripheral portion and an inner peripheral portion 4 surrounded by the inner peripheral side of the outer peripheral portion, an outer peripheral underground structure construction step of constructing an outer peripheral underground structure 7A in the outer peripheral portion, and an inner peripheral underground structure construction step of constructing an inner peripheral underground structure 7B in the inner peripheral portion. A high strength support pile 5A is used as at least a part of the support pile, an inverted driving method is used in the outer peripheral underground structure construction step, and a forward driving method is used in the inner peripheral underground structure construction step.SELECTED DRAWING: Figure 9
