BASE ISOLATION METHOD FOR EXISTING BUILDING
PROBLEM TO BE SOLVED: To provide a building base isolation method for base-isolating an existing building and making it highly earthquake-resistant, with lower costs and simpler construction processes than conventional methods.SOLUTION: A base isolation method for an existing building comprises the following steps for: constructing an earth retaining wall 2 in a ground G around a building 1 that has a basement floor, so as to surround the building 1; forming a space 3 by excavating the ground G between the earth retaining wall 2 and the building 1; and filling the space 3 with water 6 for applying buoyant force F to the building 1, thus realizing sliding base isolation.SELECTED DRAWING: Figure 4
【課題】従来よりも低コストで工事の簡易化を図りつつ、既存構造物を免震化して高い耐震性能を付与することを可能にする建物の免震化工法を提供する。【解決手段】地下階を有する構造物１の周囲の地盤Ｇ中に構造物１を囲繞するように山留め壁２を構築し、山留め壁２と構造物１の間の地盤Ｇを掘削して空間３を形成し、空間３に水６を貯めて構造物１に浮力Ｆを作用させ、滑り免震化する。【選択図】図４
