FLOATING BODY BASE-ISOLATED STRUCTURE AND SATURATED SAND CONTROL SYSTEM
PROBLEM TO BE SOLVED: To enable a stable bearing capacity to be secured for a structure in ordinary cases, and enable a base isolation effect to be effectively exerted by a slip only during earthquakes.SOLUTION: A porous floating body base-isolated structure, which bears a load of a structure 10, includes a bearing layer 2, side walls 3 that are provided at intervals around the entire perimeter of the structure 10 supported on the bearing layer 2, and saturated sand 4 that is set in a saturated state and placed in a pit part 5 constituting an area surrounded by the bearing layer 2 and the side walls 3. The relative density of the saturated sand 4 is set to be in the range of 20-50%.SELECTED DRAWING: Figure 1
【課題】常時は構造物に対して安定した支持力を確保することができ、地震時にのみ滑りによる免震効果を効果的に発揮することができる。【解決手段】構造物１０の荷重を支持するとともに、支持層２と、支持層２上に支持された構造物１０の周囲に間隔をあけて全周にわたって設けられた側壁３と、支持層２および側壁３によって囲まれた領域をなすピット部５に打設される飽和状態に設定された飽和砂４と、を備え、飽和砂４の相対密度が２０〜５０％に設定され多孔性の浮体免震構造を提供する。【選択図】図１
