METHOD FOR ESTIMATING COMPRESSIVE STRENGTH OF CONCRETE
PROBLEM TO BE SOLVED: To provide a method for estimating the compressive strength of concrete capable of accurately estimating the compressive strength of concrete.SOLUTION: By opening a window 2a, 2b, 2c, or 2d formed in an arch center 1, an elastic coefficient of a part of lining concrete 10 is measured by striking survey. On the basis of the measured elastic coefficient, using a previously obtained relational expression between the elastic coefficient and the compressive strength of the concrete, the compressive strength of a part of the lining concrete 10 is estimated, and whether the compressive strength is at least a predetermined compressive strength or not is determined.
【課題】コンクリートの圧縮強度を精度良く推定することができるコンクリートの圧縮強度の推定方法を提供する。【解決手段】セントル１に設けられた窓２ａ、２ｂ、２ｃまたは２ｄを開けることにより、打球探査によって、覆工コンクリート１０の一部分の弾性係数を測定する。測定された弾性係数に基づき、予め得られたコンクリートの弾性係数と圧縮強度との関係式を用いて、覆工コンクリート１０の一部分の圧縮強度を推定し、その圧縮強度が所定の圧縮強度以上であるか否かを判断する。【選択図】図２
