GROUND STRENGTH CALCULATION DEVICE AND GROUND STRENGTH CALCULATION PROGRAM
To provide a ground strength calculation device and ground strength calculation program that can determine ground strength accurately while excavating the ground.SOLUTION: The ground strength calculation device according to the present invention measures ground strength using an excavation machine that excavates the ground by applying rotational forces and intermittent impacts to a drilling tool. The ground strength calculation device includes: an impact times acquisition unit that acquires the number of impacts by the drilling tool per unit time; a speed acquisition unit that acquires the excavation speed of the drilling tool; an acceleration acquisition unit that acquires the maximum acceleration amplitude for the drilling tool per unit time; and a calculation unit that acquires a strength index calculated from the number of impacts (time/second)/the drilling speed (meter/second)*the maximum acceleration amplitude (meter/second).SELECTED DRAWING: Figure 4
【課題】地盤を掘削しつつ、地盤の強度を正確に判断することができる、地盤強度算出装置及び地盤強度算出プログラムを提供する。【解決手段】本発明に係る地盤強度算出装置は、削孔具に回転力と断続的な打撃力とを加えることで地盤を掘削する掘削機を用いて、地盤の強度を計測する地盤強度算出装置であって、前記削工具による単位時間当たりの打撃回数を取得する打撃回数取得部と、前記削工具の掘削速度を取得する速度取得部と、前記削工具の単位時間当たりの最大加速度振幅を取得する加速度取得部と、前記打撃回数（回／ｓ）／前記掘削速度（ｍ／ｓ）×前記最大加速度振幅（ｍ／ｓ2）により算出される強度指標を取得する演算部とを備えている。【選択図】図４
