BASE ISOLATED STRUCTURE OF UNDERGROUND CONSTRUCTION AND CONSTRUCTION METHOD OF BASE ISOLATED STRUCTURE OF UNDERGROUND CONSTRUCTION
PROBLEM TO BE SOLVED: To provide a base isolated structure of an underground construction and a construction method of the a base isolated structure of the underground construction capable of reliably and effectively ensuring stability of the underground base isolation structure for long period of time by reducing the stress applied to the underground construction such as a cut-and-cover tunnel at an earthquake.SOLUTION: The base isolated structure includes an underground base isolation wall 4, which is formed of a cray base material having the water-swelling property, a generally vertical wall-like shape or pile-like shape, with a depth of embedment from a liquefaction layer 1a to a non-liquefied layer 1b at the lower end between an underground construction 2 which is constructed in the liquefaction layer 1a of the ground 1 including the liquefaction layer 1a on the non-liquefied layer 1b and the peripheral ground 1 of the underground construction 2.
【課題】より確実且つ効果的に、地中免震壁構造の長期安定性を確保でき、地震時の開削トンネルなどの地中構造物の応力低減を図ることが可能な地中構造物の免震構造及びこの地中構造物の免震構造の構築方法を提供する。【解決手段】非液状化層１ｂの上に液状化層１ａを備えた地盤１の液状化層１ａ中に構築される地中構造物２とこの地中構造物２の周辺地盤１との間に、吸水膨潤性を有する粘土系材料からなり、略鉛直の壁状または柱状で、且つ液状化層１ａから非液状化層１ｂに下端側を根入れして構築された地中免震壁４を備える。【選択図】図１
