Zusammenfassung:	To compress bedrock around underground structures.SOLUTION: A compression device 100 for bedrock R surrounding an underground structure 1 has multiple strands S extending radially from the underground structure 1 inside the bedrock, and multiple fixing tools 10 for applying tension to the multiple strands S and compressing the bedrock R1 inside the outer ends of the multiple strands S.SELECTED DRAWING: Figure 10 【課題】地下構造物の周囲の岩盤を圧縮させる。【解決手段】地下構造物１の周囲岩盤Ｒの圧縮装置１００は、岩盤の内部を地下構造物１から放射状に延びる複数のストランドＳと、複数のストランドＳを緊張させ、複数のストランドＳの外側端部より内側の岩盤Ｒ１を圧縮させる複数の定着具１０と、を有する。【選択図】図１０
