摘要： PURPOSE:To stably keep a tall building constructed on a weak ground for a long period by working the buoyancy of a resin foamed block laid in a frame body to the whole foundation as a pulling force. CONSTITUTION:A plurality of steel sheet piles are embedded in a weak ground 1 to form a frame body 12. A resin foamed block 13 is laid in the frame 12. The maximum pulling force received by the resin foamed block 13 from the weak ground 1 is substantially equilibrated with the weights of a foundation member 18 and a construction 19 on the foundation member 18. Since the foundation member 18 and the construction 19 are supported by the buoyancy of the resin block 13, the consolidation settlement over a long period is prevented. The ratio of the length of the steel sheet pile forming the frame body 12 to the depth of the resin foamed block 13 is set within the range of 2:1-50:1. Since the frame body 12 is embedded deep in the weak ground 1, the opposing force to horizontal and bending moments is increased.

摘要： PURPOSE:To eliminate the need to particularly reinforce the rigidity of a connecting part by stacking blocks comprising plastic foams at the connecting part of a tunnel and a wing plate to efficiently decrease bending moment exerted on the connecting part. CONSTITUTION:The ground 1 is excavated to construct a tunnel 3 by successively connecting arch-shaped culverts 2, following which wing plates 4, 4 are respectively erected on either side so as to be formed integrally with the culvert 2. Next, blocks 10 comprising plastic foams are stacked on the free end side F of the wing plate 4 in an approximately truncated quadrangular pyramid- shaped region which is gradually inclined upwardly toward the inner part of the tunnel, parallelly with the center line thereof. After a predetermined number of blocks 10 are stacked in a range of stacking layers E, a civil sheet is laid on an upper layer to effect soil dressing. Ordinary soil and sands are backfilled in the vicinity of the culvert 2. On the side C of the connecting part of the plate 4 with the culvert 2, a large earth pressure is exerted, while the earth pressure is reduced on the side of position A near the free end side F and the whole load is positioned nearer to the side of the tunnel, and hence a maximum bending moment exerted on the part C becomes smaller.
